Can you match the finished stones to the rough stones? OK, the green one is easy. I'll give a clue - the largest rough stone is turned sideways. And, only one has no copper Schiller. So, that one's easy. What about the rest ?
I cut this large piece of Arizona Peridot into a 4.3 carat 10 mm x 8 mm emerald cut and then set the stone in this 14K yellow gold man's ring, for my uncle in Oklahoma.
Here is a lovely purple-blue Tanzanite that was badly scratched. A fellow jeweler pulled it out of his client's ring and sent it to me. See the difference after I re-cut and polished the crown without touching the pavilion or outline of the stone !
