These are two examples of Mark's hand carved black jade rings. These are hand carved Wyoming Edward's Black Jade rings with flush set sapphires and tourmaline made by Mark. This material is near impossible to find in the current gem market. The wonderful black jade has no impurities, is jet black and takes a great polish. Unlike many people who use tumblers to do the finishing on hand carved rings, Mark does every aspect of the shaping & finishing by hand.
