Extremely RARE Malachite cab in this one. The orbing in this stone shows the superior quality of this material. As malachite is extremely dangerous to cut, you do not see a lot of lapidaries cutting cabs. Most malachite is cut over seas. Not ours! Ours is cut in the USA! Our master lapidary certainly produced a jewel with this one! Set in a handmade sterling. Chain not included. This is quite the piece!
