A gemmy, lustrous, doubly-terminated crystal of quartz with some fluid inclusions with mobile bubbles, that are not fluorescent. In good condition with some small erosions at the terminations.

According to the associated label it is from “Ambouri”, Mali. Such clean crystals from Mali have been occasionally seen in the market, but no detailed locality is still known. Maybe it is from Mbouri (Mopti Region, Mali).
