Microcline (var: Amazonite) fossil dodecahedral crystals of Demantoid sit

dodecahedral crystals of Demantoid sit atop a thin layer of fibrous off-white color Chrysotile on host rock matrix

and a superb representation of the species and the locality

I like to call them “black beauties”) is the fact that they’re not always terribly aesthetic

but I was actually the one who first reported (through analysis) that they are indeed Scorazlite (the iron analogue of Lazulite)

Microcline (var: Amazonite) fossil dodecahedral crystals of Demantoid sitA decent thumbnail sized specimen of Amazonite with a handful of fairly sharp, semi lustrous, gentle blue green colored crystals and no matrix. The piece is clearly contacted, so it's mostly a reference specimen, but the main Amazonite crystals on the top of the piece are well terminated and look nice when viewing from above. Specimen # AMAZWH111926
