Dumorierite is a very rare aluminum borate silicate mineral that is found in the form of masses, small prismatic crystals, or fibrous inclusions within quartz. It is primarily a beautiful dark blue color, as in these earrings.
The earrings are about 1" in length and are sterling silver for the adornments.
