Parallel growth of Arfvedsonite crystals whose morphology is different from the most well known for this locality, with a shorter prism and blacker color. The crystals are bright, with polycrystalline terminations and are on feldspar matrix. We’ll send a copy of the analysis to the buyer. Djebel Ewargizen, Imilchil, Anti-Atlas Morocco (01/2012) Specimen size: 9.5 × 9.2 × 5.5 cm = 3.7” × 3.6” × 2.2” Main crystal size: 6.2 × 2.7 cm = 2.4” × 1.1”
Arfvedsonite with Feldspar
-
A rare association of Arfvedsonite with Stilbite-Ca. The crystals have very well defined faces and edges and some of them are doubly terminated. They are on matrix with bowtie-like Stilbite-Ca aggregates and small Fluorapatite crystals. Imilchil, Anti-Atlas Morocco (04/2013) Specimen size: 8.2 × 8 × 6 cm = 3.2” × 3.1” × 2.4” Main crystal size: 4.4 × 2 cm = 1.7” × 0.8”Arfvedsonite with Stilbite-Ca
