I am always wary of 'new' rocks lol, and I always try and check the website out before I believe any information given there. From a geologists pov I use mindat
http://www.mindat.org/min-29045.html or one of the big universities web libraries.
So many of these new crystals are chemically identical to ones already discovered and named, but just found in a different mining location, then given a creative dust of marketing and advertising re-emerge as wonderous 'new' healing crystals which are suddenly in great demand with a surge of interest caused by forums and websites.
On buying it.... if you fancy it for curiosity value then go for it, but in many ways your money is better spent on other healing rocks.
