Andradite (variety demantoid chromium rich).
E66FD2: Andradite (variety demantoid chromium rich)
The Italian Demantoids are really good, but this one does not miss the mark by far, transparent, aerial on the matrix of white calcite.

Andradite (variety demantoid).
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. The crystals, on matrix, are very clear and bright, have a good green color and a curious flattened shape. The locality was not well known until recently, and habit of the Demantoid is really unusual.
This specimen was published in the magazine ‘Le Règne Minéral’ number 90, page 42.
