Amblygonite is a rare phosphate mineral found occasionally in Brazil. I got this piece as part of the Hawthorneden stock, because Frank had bought several pockets of Amblygonites over the years. Of all the pieces that we got, this was the only one on matrix. For what it is, this is a really unique, hard to find specimen. The Amblygonite crystal is growing up in between two smoky quartz crystals. It's in great condition.
