Named after its discovery locality circa 1917, this is an old matrix specimen showing several veins of striated, parallel-grown crystals of this rare silicate. The Riversideite is embedded in matrix with gemmy olive-green vesuvianite crystals. Surely, there are many veins of the material distributed throughout this large specimen, were it to be broken up for study or resale.
