Over 99% of all Emeralds in the market undergo a clarity enhancement process. During this treatment emerald’s fractures are filled with oil. It’s common and acceptable practice in the world of Emeralds that can have a positive effect on a gemstone’s overall appearance.
More surface-reaching fractures in Emerald means more oil may enter. The level of oil treatment is normally disclosed upon sale and can be determined by the number of gemological laboratories worldwide. We are very proud that almost 50% of our Emerald inventory doesn’t require any clarity enhancements since these Emeralds are extremely rare. But of course, there are stones that need to be oiled.
Let’s see our short video of the Emerald Oiling Process that we usually do in our in-house faceting factory.
