This beautiful and unusual specimen has a core of glassy and colorless gypsum crystals up to 1 cm in length. A druse of royal blue azurite, to .5 cm in length is on the smaller gypsum crystals and included within the larger ones, giving the whole specimen a wonderful color contrast. I have seen this material over the years, in trickles to the market. Never have I seen one of this size, quality, and overall showiness.It is, to me, a unique and interesting azurite occurrence in a combination that is for some reason simply almost never seen. Out of all the specimens of this material I have sene over the years, this one floored me for its overall quality and impact.
