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.
The French word “Peridot” is originally derived from “faridat” in Arabic, meaning gem. Ancient peridot can be traced back to Egyptian jewelry in the 2nd millennium B.C. The stones came from a deposit on a small volcanic island in the Red Sea, some 45 miles off the Egyptian coast, which was not rediscovered until about 1900 and has since been exhausted.
Peridot is gem-quality “olivine,” a common mineral in mafic and ultramafic rocks. Formed as a result of volcanic activity deep inside the earth’s surface, gem-quality peridot is a rarity in olivine.
The demand for this beautiful stone was reignited a few years ago when peridot deposits were found in the Kashmir region; and the stones were so incredible in color and transparency.
Although it’s one of the only gemstones found in just one color, the intensity and tint of the olive green hue depends on how much iron is within the crystal structure. Varying from yellow to olive to brownish-green, peridot is most valued as a dark, emerald-resembling gem.
If you were born in August, you may be fortunate enough to receive a peridot as a birthday gift. If received as a ring, wearing this birthstone carefully is important, as it isn’t as tough as it looks. Prone to breaking, peridot are better suited for bigger necklaces; a bonus being that larger stones carry a richer color.
Throughout history, peridot has been thought to possess great mystical powers to ward off anxiety and inspire happiness, strength and loyalty. It is also believed to promote success in relationships and marriage.
Once called the “gem of the sun” in ancient Egypt because of its dazzling appearance in the sun, the curiosity and enchantment that surrounds peridot has made this radiant gemstone timeless.
