Hydroboracite is a rare hydrated borate. This is a very fine specimen of diverging sprays of large, waxy luster, blades nicely set in matrix. I like the way the largest spray is front and center, in the most prominent position. Old material from Death Valley. Rarely crystallized in such quality as you see here.
