Comment: Unless you are an experienced rock-hound you may not have heard of Euclase. I say 'rock-hound', not 'gem-hound', because the chances are higher to have met Euclase as a collector-mineral, in its rough crystal-form, but chances are much slimmer in facet form. Further-more you would have come across it in pale yellow or colorless form. This here intense blue, shocking for all sapphire and spinel, is the rarest form of Euclase, found only in Columbia together with Muzo emeralds, or, as this, from the 'Last Hope Mine' in Zimbabwe (no, it is 'Lost Hope' but such bad marketing). Euclase is a durable jewelry gem 'en par' with zircon or topaz AFTER it has been cut, but, and that is a giant BUT, because of its high cleavage few dare to facet this precious matter, and fewer still succeed. For this reason, and for the fact that the cut is flawless in its result, no window, pleasant shape, luster, and good dimensions, we graded its cutting as 'excellent'. Though not a precision cut, but a traditional hand-cut, the unknown lapidary deserves any possible compliment for the surely excruciating hours he must have spent cutting a crystal worth his year's salary. How rare is such a gem? Think 'blue diamond', and close you are (freed from cash-flow-obligations, I would price it as such, too, say at $750.000/ct, but who is free from cash-flow-terror?). Search the web, or more exhausting mineral-shows, and all the rare-gem-geek web-sites, there is nothing remotely comparable around. The eye catches some green sparks in the blue though the camera doesn't, inclusions are visible only under the lens. Its relatively low density makes 1.5 carat a big looking gem, 8x7mm, just perfect for an ultra-rare pendant (protected but visible), a piece of jewelry even more special than an extra perfect sapphire. The ultimate homage to a very unique person, or the rarest of occasions. As far as wealth-display goes, this is the most inconspicuous and understated value-storage-system imaginable. There will be one or two other Euclases coming but none will be this perfect.
