My limited experience was good, not excellent. I would however
advocate buying locally. My two main sources that I have had
excellent experience with are D&J Rare Gems, and The Gem Trader. D&J
have at least two claims that I know of in the States and do their
own gem cutting, however, all their gems are not cut by them, some
are outsourced. The Gem Trader also runs some Ebay auctions from time
to time, I was able to acquire two beautiful stones from their
Best of luck.
