I’ve been absolutely loving my journey into the world of gemstones. Every piece I work with teaches me something new, and I’m finding that the more I learn, the more I appreciate their beauty and history.
Today, I want to share just a little bit about emeralds – one of the most fascinating gemstones I’ve been studying.
Emeralds are part of the beryl mineral family, which also includes aquamarine, morganite, and heliodor. Of all the beryls, emerald is the most famous and the most valuable. Its vivid green color has made it a symbol of prestige for centuries.
But what actually makes a gemstone an emerald?
It all comes down to chemistry. True emeralds get their green color from trace amounts of chromium and/or vanadiumwithin the crystal structure.
-
Chromium gives a vivid, pure green to bluish-green hue.
-
Vanadium can also create green, sometimes with slightly different undertones.
-
Iron, when present, can shift the color toward bluish-green or reduce the saturation.
If a green beryl doesn’t have enough of these coloring elements — or the color isn’t intense enough — gemologists will classify it simply as green beryl instead of emerald. This can lead to some debate in the gem world about exactly where the emerald category begins and ends.
As you can see in the picture, I have some emeralds here with me today that are not highly translucent. Even though emerald is a precious gemstone, it can appear in a wide range of clarity levels, from very transparent to more opaque. Personally, I think these more natural, earthy pieces have a unique charm all their own.
Whether perfectly faceted or in a more rustic form, emeralds remain the most popular and prestigious member of the beryl family — a gemstone that continues to fascinate jewelers, collectors, and gem lovers around the world.
