Item Description

A few years ago we obtained a small parcel of what turned out to be some of the richest and most uniform color Phosphosiderite gems that I have seen. Originally these stones were said to come from Sapucaia, Brazil, which has produced massive Phosphosiderite in the past, but we now have both visual and verbal confirmation that these stones are actually coming out of Chile. Phosphosiderite is fairly uncommon hydrated iron phosphate that is rarely seen in the gem world, so we needed to know exactly where they were from. I'm told that the reason for all the confusion as to the origin of this material may be the fact that the rough could lie in a National Park, where collecting is illegal, so the locals have done their best to use subterfuge. . Now that we know this material is both natural (we had this material analyzed, and it was verified as fine-grained Phosphosiderite). I am happy to provide a copy of the analysis to anybody who would like it), and its true origin, we feel 100% confident in offering it for sale. This gem has a "Round Cabochon" cut with a very distinctive purple/lavender hue. The is solid Phosphosiderite, with no other minerals mixed in, which is rare in my experience. I have only seen a few very tiny faceted gems of this material in my life, but cabochons such as this one are rare and attractive, not to mention worthwhile for any gem collector.
