Lazurite pseudo after Sodalite
Fayzabad, Koksha Valley, Khash-Kuran Wa Munjan District
4.8 x 3.3 x 2.7 CM (miniature)
Late Summer 2018
A brilliant blue crystal of Lazurite nicely perched on a Calcite matrix. This is quite a fine Lazurite but it is in fact much less common, it is a partial pseudomorph of a Sodalite crystal. Both minerals are known to pseudomorph each other but can have similar crystal shapes so it is hard to detect. On this crystal there is some small zones where the brilliant blue is only partly covering the whitish to more pale blue interior. The core of the crystal can be seen and is still Sodalite, This is vividly Fluorescent in those spots but the exterior blue Lazulite has no response. The crystal is up to 2.7 CM across and contrasts perfectly with the matrix. A choice crystal and intense blue pseudo.
Scapolite (purple gem crystal)
Sar-e-Sang District, Koksha Valley
2.6 x 2.4 x 2 CM (small miniature/ large thumbnail (toenail))
A deep, intense purple, very lustrous Scapolite crystal from Badakhshan Afghanistan. Tranparent to translucent and in very good condition this is a particularly choice small gem crystal. Classic habit for these rare crystals from Badakhshan, which are world class for the specie.
