This intense fancy yellow diamond crystal is a natural shape formed from two intergrown diamonds, each twinned in the macle twin law. It is complete all around, and at the same time both a specimen for the collector and a specimen of rough for a unique piece of jewelry ready to mount as is. These are almost impossible to obtain, as nearly all are cut immediately for the obvious gemstone value and easier market in selling cut stones. mass is 0.84 carats
