Had a sapphire I dug a while ago, showed it to a cutter who said that there is some good crystal in it but only enough to facet a very small stone (ie, a Lamberts cutter). So I didn't worry about it. But last night I decided "what the hell - I'll cab the thing".
Ended up being about 7mm in circumference, a bit of silk in there. In the rough and early in the cutting process, it was a beautiful shade of blue-green. But once finished and polished up, only stong backlighting would show any colour - had it been put in a setting it would just have looked black.
It was blue with a green cross so prone to being dark I guess, but neither the blue nor the green were an overly dark shade. The green cross was actually a nicer colour I thought but I couldn't orient it that way or there would have been virtually nothing left because of the shape.
I've noticed that dark garnets and coloured quartz seem to actually lighten a bit when cabbed. What is it with sapphire?
