Well, while certainly not one's normal call... it's out there.
Interesting material, almost no color dispersion, probably a throw-a-way for some. But the client wanted clear material with a slight grey cast... It really took a while , the folks at One World Gem have been supplying rough for me for a few years now and doing a great job given I'm always asking for something weird. After a couple trips overseas the owner came across the material you see in the ring. It's really rather nice, cool to the eye, and great with platinum. I haven't a clue what the material would be worth under any other circumstances.. This one has time, labor , cutting fees & too many phone calls layered on the rough to get an accurate read.
I actually have a duplicate (I had a back-up cut at the same time),
Not too sure it'll get used for anything at this point.
It's kinda like "Go find another" and who , or why would you want to?
But for this project it was the right thing...
