This is a riveting, INTENSE blue color the likes of which you will seldom see in the mineral kingdom. The thin plate of matrix is host to overlaying linarites, some flat and some sticking up at an angle, that are glassy, transparent. It is an important example of the species from a US locality and so far as I have seen (in several years of watching these trickle out in dribs), the best larger specimen from the locality on the market. It compares favorably with other worldwide finds of this species, which are few and far between. Maybe there are others, but I have not seen them and I got this from the collector a year ago in Tucson. They are so blue that you have to reset your parameters for the color - really, not hyperbole, its that crazy freaky blue. So although this seems expensive, in person if you could see it would look dirt cheap compared to prices asked typically for the Grand Reef or old English material, and its a lot sexier too...
