So much thanks to you all. Now I know. Everything I have cut so far I have either cabbed myself and saved for a faceting machine. I still have plenty of clean quartz. I feel better and more confident now to purchase lab specimens and feel confident of a nice stone. A bit more affordable to cut. But from what I see too is some lab specimens are just as rare in some cases.
What specimen would everyone suggest as for me to cut next? Suggestion of a reliable source or is ebay the best bet?
