Gemstones for Everyday Wear

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.

Gemstone of the Month: Emeralds

The long-standing fascination with emeralds may simply lie in their intense, radiant green color. Although rare in the gemology word, imperfections and inclusions are often tolerated in this beautiful stone, happily overlooked by many in exchange for the visual pleasure that this May birthstone brings. The bigger issue affecting the significant price and marketability of emeralds is the presence of a rich, dark green color.

Emeralds have a good hardness of 7.5 to 8 on the Mohs scale and belong to the large gemstone family of the beryls. Pure beryl is colorless. The colors do not occur until traces of another element are added. In the case of the emerald, it is mainly chromium and vanadium, concentrated (unusually) in different parts of the Earth’s crust. The tension created during this process produces some minor flaws in the stone – and some major ones. Only seldom is a large emerald with good color and transparency found, which is the primary reason emeralds are so valuable.

Rubies, sapphires and emeralds form the “big three” of colored stones, generating more economic activity than all other colored stones combined. In the last several years, the value of emeralds imported into the U.S. exceeded the value of rubies and sapphires combined.

Today, many emeralds are enhanced with colorless oils or resins. Although a common industry practice, it is done so with the caution of consequence, as these green treasures react very sensitively. While the hardness of emeralds protect it from scratches, its many fissures can make cutting, setting and cleaning rather difficult. When cutting takes place, the substances used or applied seals the fine pores in the surface of the gem. Removing them gives the stone a “matte” appearance. Emerald rings should also always be taken off before the wearer puts his or her hands in water containing cleansing agent and they cannot be cleaned in an ultrasonic bath.

A hard, but not tough stone, perhaps the lure of the emerald can be summed up by Roman Philosopher Pliny the Elder’s writing that “green gladdened the eye without tiring it.” True enough, the love affair with emeralds continues to evoke emotions in jewelry lovers everywhere.

 

10 Most Popular Cuts of Diamonds

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.
