Item Description
Hydroboracite is a rare hydrated borate. This is a very fine specimen of diverging sprays of parallel-growth, waxy luster, blades. Old material from Death Valley and uncommon from this noted and extinct locale. Very rarely crystallized in such quality as you see here. An outstanding thumbnail specimen.
