SV2140CBR: Aegirine with Quartz (variety smoky)
Group of Aegirine crystals that show two different morphologies: some crystals are very sharp and elongated, whereas others show elongated monoclinic crystals with very marked polycrystalline terminations. These are all associated with a doubly terminated Quartz crystal (smoky variety) with a double termination at one of the ends, with very well defined faces and edges and in perfect harmony with the Aegirine crystals.

TM68D8: Afghanite
We waited a while before offering Afghanites on our web site. Ones we have seen before were either two expensive, not very esthetic, or a pale color. Finally we were able to locate the examples we were looking for: very esthetic, aerial crystals, intensely colored, perfect, and not too highly priced. A definitive sample, with a large main crystal standing well out from the matrix and accompanied by another small crystal. It all stands out well from the white Calcite matrix.
