Svabite & Calcite

*from Langban, Sweden.
*140 x 70 x 60 mm.

Part of the apatite family. The arsenate analogue of fluorapatite. This is a rich piece with calcite (UV red). The svabite is uv golden yellow to slight orange in both LW and SW but best in SW.  Not a common mineral to come by. The blue in the photo is just the SWUV light reflecting. There is not any blue uv minerals here.
