LARGE GREY MOONSTONE RARE.I have been looking for years for a stone like this , an extremely rare top quality large (75ct) Grey Moonstone of clarity and cleanness. This stone is from Tanzania.The stone displays good transparency, with a wonderful sheen from light diffraction from the layers of feldspar (lamellae).This stone is absolutely a collectors piece. We have set the Moonstone in sterling silver, the resulting mix of the Silver and grey is beautiful. The stone weights 75ct.(32mm x 25mm). It is 5cm long and 3.1cm wide.We have put an appropriate large bale on the pendant that should accommodate all size chain.
