When it comes to fine jewelry, gemstones are the alluring stars that often steal the show. Although diamonds typically take center stage, an array of other gemstones offer a wide spectrum of colors and symbolism. Colored Gemstones originate from all over the word; This guide will delve into some of the most common gemstones you’ll see in fine jewelry, offering a new appreciation to the variety and beauty of these precious and semi-precious stones.
Recognized for their deep, rich green color, emeralds are members of the Beryl family of minerals. Highly prized in fine jewelry, the value of an emerald can often surpass that of a diamond due to its rarity and color. They symbolize rebirth and love, and their vibrant hue brings elegance and sophistication to any piece.
The majority of the world’s emeralds are mined in Colombia and Zambia. Colombia’s emeralds are highly sought after for their pure green hue, while Zambian emeralds are known for their deep, bluish-green color.
Rubies are revered for their fiery red color, representing passion and protection. They belong to the Corundum mineral family, and their durability is second only to diamonds, making them excellent choices for everyday wear. Fine rubies with little to no imperfections are incredibly rare and highly valued.
Historically, the Mogok region of Burma, now Myanmar, has produced exquisite rubies with a pure, saturated red color known as ‘pigeon’s blood’. However, Thailand’s Chanthaburi and Trat districts are also significant ruby sources, producing stones with a darker, more garnet-like color.
Sapphires, famed for their royal blue color, are part of the corundum family and come in nearly every color except red. They symbolize wisdom and nobility, making them a popular choice for ceremonial jewelry and engagement rings. These gemstones are mined worldwide, including locations such as Madagascar, Australia, the United States, Thailand, Vietnam, China, Kenya, and Tanzania. However, the three most prominent sources, known for their high-quality sapphires, are Kashmir, Burma, and Sri Lanka.
The sapphires mined from Kashmir are the most rare and valuable. The Kashmir mines were active for only about 40 years between 1880 and 1920, which contributes to the rarity and high value of these stones. Sri Lanka, previously known as Ceylon until its independence from Britain in 1948, is a significant source of vibrant sapphires. The blue sapphires from Sri Lanka, referred to as Ceylon Sapphires, are renowned for their lighter, brighter, and more vivid hues compared to the darker blue sapphires from other regions. These Sri Lankan or Ceylon Sapphires have a rich history dating back to the second century A.D., making Sri Lanka home to some of the world’s oldest sapphire mines. Their popularity peaked during the fourth and fifth centuries when they were extensively traded internationally, establishing their lasting appeal and importance in the gemstone market.
These charming purple stones are a variety of quartz, known for their wide range of purple shades. Once as expensive as rubies and emeralds, amethysts became more accessible once large deposits were found in Brazil. They are believed to promote calmness and balance, making them a popular choice for spiritual or meditation jewelry.
Brazil’s Rio Grande do Sul state is one of the world’s leading amethyst producers, with mines extracting the gem from volcanic rocks. Uruguay’s Artigas region also has large amethyst deposits, with the stones often found inside geodes in the area’s basalt flows. With a hardiness rating of 7 on the Moh’s scale, Amethyst and it’s fellow quartz varieties are ideal for pendants and earrings.
Opals are truly unique gemstones. They exhibit a range of colors in a single stone through a phenomenon known as “play-of-color.” The presence of tiny silica spheres within the stone diffracts light to create this dazzling effect. Opals symbolize hope, innocence, and purity.
Coober Pedy in South Australia is known as the opal capital of the world, with the town’s opal fields producing an abundance of precious white opal. The Lightning Ridge area, also in Australia, is known for its rare and valuable black opal.
The Boulder Opal is another variety of Opal that is quite lovely. These distinctive gemstones are unique in that the opal forms in a thin layer within the fissures and cavities of ironstone boulders. The opal layer is often left attached to the ironstone backing when cut and polished, providing a dark and dramatic backdrop that enhances the opal’s vibrant play-of-color.
The Queensland mining fields in Australia are a primary source for these beautiful boulder opals. Their captivating interplay of color and unique patterns, framed by the raw, rugged ironstone, makes each boulder opal a unique piece of art.
While technically not gemstones, pearls have been an integral part of fine jewelry for centuries. Formed within mollusks, pearls are the only gems derived from a living creature. They come in various colors, including white, black, grey, and pink, and symbolize wisdom and integrity. The deep green & rose ‘oil slick color combination known as Peacock is highly desirable among Tahitian Pearls
Natural pearls are most commonly sourced from the Persian Gulf, especially around Bahrain. Japan, however, revolutionized the industry in the early 20th century by developing methods to cultivate pearls, making them more widely available. Natural pearls are now extremely rare.
Known for their captivating sea-blue color, Aquamarines are the blue to blue-green variety of Beryl, the same mineral family that emeralds belong to. These gemstones have been cherished for their tranquility and soothing characteristics, symbolizing harmony and trust.
Historically, the most famous deposits of aquamarine have been in the country of Brazil. However, other significant sources include the African countries of Madagascar, Kenya, and Nigeria. Pakistan’s Karakoram Mountains are also well-known for producing stunning aquamarines, often found in pegmatite deposits. As with Emeralds, Aquamarines are best suited for pendants and earrings or light wear in a ring.
Tourmalines are among the most versatile of gemstones, owing to their availability in an almost endless variety of colors. From luscious greens to deep reds and even multi-colored specimens, tourmalines are beloved for their unique chromatic range. They are also known for their durability, making them suitable for all types of jewelry.
Historically, the most significant tourmaline deposits are found in Brazil and Africa, specifically Nigeria and Mozambique. However, they are also found in several locations in the United States, predominantly California and Maine. The unique watermelon tourmaline, with its green exterior and pink core, is one of the most sought-after varieties. Symbolically, tourmalines are believed to promote inspiration and happiness, lending an emotional depth to their physical beauty.
Peridot is one of the few gemstones that come in a single color: a vibrant, olive green. These gems are formed deep within the Earth’s mantle and are brought to the surface by volcanic activity. Their green hue represents nature and is believed to bring healing and protection.
Peridot is one of the few gemstones found in meteorites, though these extraterrestrial specimens are extremely rare. The world’s largest peridot deposit is located on the San Carlos Apache Indian Reservation in Arizona, USA.
Garnets are a group of minerals that come in a rainbow of colors, but they are most commonly known for their deep red hue. They are believed to represent commitment, honesty, and hope. Their durability and versatility make them suitable for various types of jewelry.
Garnets are found worldwide, with major deposits in Africa, India, and Sri Lanka. Russia’s Ural Mountains were historically the leading source of garnets, known for their distinctive emerald-green variety called demantoid. Tsavorite is also a beautiful green variety, and Spessartite is a vibrant orange!
There is a world of gemstones beyond diamonds, each with its unique characteristics, color, and symbolism. Next time you’re shopping for fine jewelry or working with a designer to create a custom piece, consider these captivating gemstones. Consulting a Certified Gemologist is also always helpful. They not only add color and individuality to your collection but also carry stories and meanings that can make your jewelry truly special.

It’s that time of year again! The holidays are upon us, and it’s time to enjoy a full season of festivities, parties, and gift-giving. Why not make things easier on yourself by gifting your loved ones with classic jewelry? You really can’t go wrong with jewelry – and with customizable options from J. Briggs & Co., like choosing which precious metal to use, that Christmas or Hanukkah bauble becomes extra special. Oh, and don’t forget to pick up a little something for yourself while you’re at it.
When picking out Christmas jewelry as a gift, make sure to choose pieces that are sentimental and can be worn year-round. A cross pendant, for example, is a classic shape that can hold a great deal of meaning when given as a Christmas gift. Plus, it doesn’t hurt if the cross is composed of several pear-shaped diamonds. When selecting a J. Briggs & Co. pendant and customizable chain, pick the platinum chain for Christmas. Might as well go all-out.

For the stylish man in your life (or a younger brother you wish would dress better), custom cufflinks are the perfect Christmas gift or stocking stuffer. If he’s a sports fan, these baseball-inspired cufflinks with precision cut diamonds have just the right balance of bling, masculinity, and that “typical guy” factor.

With eight days to fill with presents, Hanukkah jewelry gifts are a surefire way to shake things up a bit; and deep blue sapphires will definitely stand out from the rest. Add in a hint of ice – aka diamonds – and you’ve got a game winning combination. A beautifully crafted pendant with diamonds and sapphires makes an elegant statement, yet it’s still simple enough for everyday wear.

A large cocktail ring is super classy when holding a martini glass, but fashionistas can also create their own unique look with stackable rings. And in this case, we’re not referring to those throwaway stackable rings made of plastic or nickel. This Hanukkah, wrap up a stunning sapphire eternity band (or several) for a memorable gift. Whether they’re worn stacked or solo, a sapphire and diamond band is an exquisite addition to any lady’s jewelry wardrobe.

Holiday shopping is exhausting – go ahead and reward yourself with some shiny new Christmas jewelry. Christmas-themed jewelry can be so kitschy, but incorporating a subtle holiday motif into your jewelry collection is charming. Instead of the normal tennis bracelet, treat yourself to a glitzy HopeStar diamond bracelet that mimics the look of snowflakes with eye-catching sparkle. It’s the ultimate accessory for any holiday party or special occasion.

If a barrage of diamonds isn’t your thing (don’t worry, we won’t judge), try a strand of multicolored pearls peppered with diamond HopeStars. Worn with the perfect little black dress, this necklace is a total showstopper. Rather than the cliché red and green combo, a pastel array of South Sea, Tahitian and freshwater pearls add a splash of color that you can wear during Christmas, Hanukkah and beyond. Sure, you could give these pearls away as a gift – but we recommend stashing them away for yourself.

Gemstones for Everyday Wear
J. Briggs & Co.
The saying “diamonds are forever” has its basis in fact. Among the sturdiest of gemstones, diamonds stand up to punishment better than many other stones. In fact, diamonds rate a score of 10 on the Mohs gemstone hardness scale, the highest rating of any gem. That’s one of the reasons that diamonds are the timeless, popular choice for all types of jewelry, from engagement rings to diamond studs.
But hardness is not the only measure of a gemstone. Toughness is also a factor to consider when deciding whether to wear your gemstone out to a certain occasion or during everyday activities. While hardness refers to a gem’s resistance to scratching, it doesn’t necessarily describe its durability. A gem’s toughness relates to its resistance to cleaving, chipping, or wearing. Some gems simply crack or wear down more easily than others.
In addition to hardness and toughness, it’s important to consider the piece of jewelry in which a gemstone is set. Rings see the most abuse of any jewelry because we use our hands so much and the gems end up being exposed to more bumps and bruises. Other pieces, like earrings and pendants, are less likely to come into contact with other surfaces, keeping the stones within them safer than those in a ring.
When considering gemstones that are most suitable for rings, a Mohs hardness rating of 7 or higher is generally deemed suitable for mounting in a ring setting, but toughness does come into play. For example, while emeralds rate an 8 on the Mohs scale, they are prone to fracturing easily. Certain types of settings can prove protective to vulnerable gems, so choosing the right setting in which to mount your gemstone is a conversation to have with your jeweler when designing a ring.
Gemstones that don’t rate high in hardness and toughness can still be mounted in rings, but should be worn occasionally and with greater care than a ring would normally see in everyday wear. After all, a ring sees very different action during a night out on the town than it does while cooking or cleaning at home.
It’s important to know the specifics of your gemstones. Some, like pearls, can be susceptible to chemicals because they are porous. Others, like peridot and aquamarine, shouldn’t be exposed to acids. Opals are very susceptible to damage being low on both hardness and toughness. To better understand your gemstones, their wearability, and how to care for them, consult your jeweler (or certified gemologist). If you’re designing a new piece, your jewelry designer can help you take into account the features of the gemstone you are mounting and work with its unique features to design a setting and piece that is the most protective.
Diamonds are both hard and tough (plus they go with just about everything!), making them ideal for wearing on most occasions. And you might not realize that diamonds come in more than one color, but that’s a topic for a future blog! Below is a short list for your reference. If you have questions about the suitability of your gemstones for everyday wear or if you’re looking to set a stone in the an appropriate setting to get the most use from it, contact designer and certified gemologist J.Briggs to set up a consultation.
Adopted from the Greek work “adamas,” meaning invincible, diamonds come in a wide range of colors such as black, blue, green, pink, red, purple, orange and yellow.
If you have a hard time remembering what different cuts of diamonds look like or are called, here’s your perfect cheat sheet for the Top 10 Cuts for the birthstones of our April babies:
ROUND: The most popular shape — owning nearly 75% of all diamonds sold — round cuts are considered superior to ornate shapes. At the proper reflection of light, their maximum potential brightness outshines the competition.
PRINCESS: The princess cut diamond is the most popular ornate diamond shape, especially for engagement rings. Like rounds, princess cuts are practical choices because of their flexibility in working in almost any style of ring.
OVAL: The oval diamond has an elongated shape often creating the illusion of being a larger diamond.
MARQUISE: This cut is football-shaped. Because the marquise diamond is long and narrow, it can also create the illusion of greater size. Carat for carat, the marquise diamond has one of the largest surface areas of any diamond shape.
PEAR-SHAPED: The pear-shaped diamond is a combination of a round and a marquise shape, with a tapered point on one end. In a perfect world, this type of diamond should have very good symmetry, with the point lining up with the apex of the rounded end, and the shoulders and wings (the upper and lower curves on the right and left side of the diamond) should be uniform.
CUSHION: The cushion cut diamond combines a square cut with rounded corners, much like a pillow (its namesake!). This classic cut has been around for almost 200 years. Refinements have led to a resurgence in popularity for this lovely cut.
EMERALD CUT: The emerald cut is quite unique. Although not designed to sparkle, by interchanging light and dark planes during refinement, a “hall-of-mirrors” effect is achieved — a beautiful illusion that creates extraordinary broad flashes of white light to contrast the dark planes. This “step cut” process varies from the more traditional “brilliant cut” method, which provides more sparkle. Emerald cut diamonds will make inclusions or body color easier to see.
ASSCHER CUT: First produced in 1902 by the Asscher Brothers of Holland, an asscher cut diamond is similar to the emerald cut, but in a square shape with larger step facets, a higher crown, and a smaller table (the uppermost, flat surface of a diamond). This combination often produces more brilliance (sparkle!) than the emerald cut.
RADIANT CUT: The radiant cut creates a vibrant and lively diamond with a modified square shape, a nice bridge between a cushion and a princess cut, making it look stunning when set with both rounded or square cornered diamonds.
HEART SHAPED: There’s no mistaking a heart-shaped diamond. Popular in solitaire pendants as well as rings, heart-shaped cuts are best utilized with diamonds more .50 carats in size, since the heart shape is more difficult to recognize in smaller stones, once set in prongs.
Everyone approaches the world of jewelry in their own way. With so many wonderful options, it is the perfect medium to express your personal style, commemorate a life event, send a message or simply accessorize. But let’s face it; things change. Trends go in and out, families get larger or smaller, relationships fizzle, new ones ignite…what to do with the jewelry? I assure you, it does no one any good to leave it in a box unseen for years. And check this out: diamonds are between one and three BILLION years old! They do not expire. Let’s talk options.
The opportunities for re-designing older jewelry and giving it new life are endless. Taking a stone from a necklace and turning it into a ring, for example, can be an affordable option. Removing stones from several dated jewelry pieces and combining them into one modernized, custom pendant that fits your look and lifestyle, is another way to give your gems a new home. And as an added bonus, the metal from the old jewelry can be traded in as credit toward the new piece. Having a box of unworn jewelry is like having a box of cash just sitting there!
In other instances, you may receive gorgeous heirloom jewelry that has been passed down from generation to generation, yet you want to change a few aspects of it to make it your own and think, “How can I make this my own without losing Grandma along the way?” Preserving the integrity of the piece while customizing it to the current wearer takes a jewelry artist who can envision the bridge between the two.
Here are some tips on transforming your estate jewelry into works of art:
1. Don’t sell it! Make it your own…and work it. Selling your jewelry only yields 30-40% of its value, on average. Instead, turn it into something you’ll be excited to show off. This is especially true for diamonds, where the return can be even lower.
2. Gift it to your daughter. There is nothing more special than creating a custom design to give to your child. Engraving can add a special touch, as can adding birthstones.
3. When in doubt…remount! Remounting is a great way to preserve your jewelry. It gives you the opportunity to merge estate jewelry with your current pieces to create a new specialty design.
Taking your jewels from ho-hum to heavenly is worth the time and effort it takes. Mother earth has given us the gift of these beautiful treasures, and they are perfect for recycling, & reinventing. Seeking out a professional designer and certified gemologist who concentrates in this genre will ensure you end up with a stunning piece that represents you, the wearer.
Ask any woman what her favorite gemstone is, and you’ll most likely receive replies that range from diamonds and emeralds, to rubies, amethysts — perhaps even the popular tourmaline. And as gorgeous as those are, we thought it was time for a few less well-known rocks to have their moment in the sun! Check out two gemstones we think will surprise you with their beauty, while leaving you “ooohing” and “ahhhing” for more!
The second biggest seller in 2014, sapphires have always been a favorite gem. Blue ones, that is.But sapphires can also be found in yellow, white, green, purple, black and…drum roll please…a gorgeous, deep PINK.
Sapphires deepen in color as the quantity of chromium in them increases. In a pink sapphire, the deeper the pink color, the higher their monetary value, as long as the color trends toward the red of rubies. Second in hardness only to diamonds, sapphires are perfect for everyday jewelry and we think you’ll find pink sapphires quite the conversation piece!
Perhaps you haven’t heard of this brilliant beauty, but tsavorite garnet is type of stone in the “grossular” group, which is comprised of calcium and aluminium. Named in honor of the world famous Tsavo National Park in Africa, this gem’s homelands between Kenya and Tanzania have been the primary source of tsavorite since it was first discovered in 1967.
Tsavorite garnet’s rich green color make it almost mistakable for an emerald – until you sigh in relief at its far less-expensive price tag. A gemstone with a robust hardness, tsavorite is unlike many others in that it is neither burnt nor oiled for its shine. Any such improvements or alterations are unnecessary, as tsavorite garnet is a pure piece of Mother Nature in its natural state.
