This is a parallel-growth cluster of bladed, glassy and gemmy, nearly colorless crystals of volkovskite with minor hilgardite crystals providing a bit of red color to the edges. This is the largest and finest crystal spray which was put up for sale from a small group of no more than a few dozen good quality specimens, that was recovered by a worker in the mine a few years ago. In all the past working at this large economic mine, which has produced the world's greatest examples of boracite and hilgardite in the past, I had never seen an example of this species. It was, seemingly, a one-shot pocket found like a needle in the proverbial haystack. ex. Tim Sherburn collection
