All about Emeralds

Prized since ancient times, a fine emerald can be more costly than a high quality diamond of the same carat weight.

Emeralds are green members of the popular beryl family of minerals. The green color happens when pure, clear beryl contains either chromium or vanadium.

Beryl happens in lots of other colours, with shades contingent on the impurities that Mother Nature has whisked into its otherwise clear formula. Blue beryl is regarded as aquamarine. Yellows are usually simply called yellow beryl and golden beryl. The term bixbite refers to red beryl, a variation that is even more rare than emeralds.

Common Emerald Treatments

Even though treatments are common and accepted, they should be disclosed to buyers.

* Some coating oils are clear, some are tinted green to make the emeralds more vivid.

When high-demand gemstones are scarce and costly, humans attempt to create products that look like the real deal.

The way manmade emeralds are grown has changed, but they have been produced for a number of years. Some of the stones actually have inclusions that make them look natural. Always ask if gemstones are made or natural, and if you are purchasing a pricey gemstone have it checked by a testing lab.
