i've never ordered from them but i do remember looking at their stuff once.....i don't know, i just get this weird feeling when all the stones of one particular type all look the same. they have more than 20 7-mm "russian chrome diopsides" with very little difference in color. i'm the suspicious type though.
i forgot to mention, i checked their return policy - it's 7 days and subject to a 10% restocking fee. i occasionally make wacky, cheap ebay purchases myself so if you do purchase from them just remember the return policy.
