NGT67AO3: Andradite (variety demantoid)

Andradite crystals (demantoid variety) with very well defined trapezohedron and rhombododecahedron forms, translucent, with a bright luster and an intense and deep green color, on matrix. Worth noting is its abundance of crystals since these Iranian demantoids usually occur as isolated crystals.

EV57N8: Andradite (variety demantoid)

A novelty in Ste. Marie 2009. Group of crystals with a dominant dodecahedron and the faces of a trapezohedron on the edges.
