Grossular


Grossular is a calcium aluminum silicate and a member of the garnet group (Grew et al., 2013). Abraham Gottlobb Werner (1749-1817) proposed this species name, as recorded in the 1811 Handbuch der Mineralogie by Professor Christian Hoffmann. The mineral name alludes to the botanical species Ribes grossularium, the gooseberry, its color resembling that of the mineral from the type locality.

This is a cinnamon colored crystal of grossular with good transparency. Gem traders call such examples hessonite. This crystal cluster has a prominent 15 mm crystal showing both dodecahedral and trapezohedral forms, about 60% complete. There are contacts on the main crystal where other crystals were likely once attached. Gemmy and appealing!
