These grossular crystals are clustered together with light balls of prehnite and a few small epidotes. The grossulars are very dark brown, sharp and lustrous.
There are light-coloured needle-like inclusions in the grossular crystals, quite possibly of an amphibole group mineral (visible in the third photo). In excellent condition, a couple of small missing epidotes and a few incomplete crystals at the periphery (with magnification one can find a few nicks). Great contrast with the prehnites – these are such sharp grossulars.
About These Grossular Specimens
These were found in 2016 from a new Arrondissemant Diako locality, Diabe Sira. Unlike most garnets from the region, the specimens from this find are plates of crystals on matrix – they are very attractive.
