Item Description

Irai is well known for elongated scalenohedrons, perched inside amethyst pockets in some cases, or growing in isolated sprays on thin basalt shells from the lava tubes here. I have not, however, seen anything from here like this before. It is a spray of sharp, almost acicular calcites poking out like hedgehogs on the rock matrix. Each of the spherical clusters is complete all around, even the backside. The piece is in amazing condition, almost pristine despite its exposure to damage. Unusual, for any locality, this just strikes me as all the more interesting because it is so different from the thousands of Irai calcites I have seen before
