This is a large phosphosiderite skull that we grabbed from Starborn Creations in Denver. It's about 4" long and is 662g. It's a beautiful orchid-purple. Phosphosiderite is usually carved into cabochons for jewelry. This is the first skull I've seen. It has a similar calming feel to lepidolite, but lighter, and the color is really unique. This one is a stunner! Price includes insurance.
