2.9" Nepheline and Schorlomite Garnet Association - Morocco

This is a rare association of hexagonal nepheline (nephelite) crystals with schorlomite garnets, that was collected from the Meknes-Tafilet region of Morocco. The nepheline crystals are grey-green in color and formed from a matrix that's rich in black schorlomite garnets. This crystal association occurred in a vug (cavity) within the Tamazeght Mountain Range of Morocco.

Andradite is a species of the Garnet group, and although not as well-known as some other types of Garnets such as Almandine or Pyrope, it is the most lustrous. It tends to be opaque, so most andradite does not make for good gemstones. It occurs in skarns developed in contact metamorphosed impure limestones or calcic igneous rocks; in chlorite schists and serpentinites and in alkalic igneous rocks (typically titaniferous).

Garnets are nesosilicates having the general formula X3Y2(Si O4)3. There are many species of garnet which are pyrope, almandine, spessartine, uvarovite, andradite and grossular (varieties of which are hessonite or cinnamon-stone and tsavorite).
