This is a solid intergrown boracite matrix lined with lustrous and translucent, light blue-green boracite crystals to 5 mm across. Atop, it has a 2x3 cm window-like vug which is lined with lustrous, orange hilgardite to 2 mm across. Both species are here in excellent representation and in fact the hilgardite is unusually well-crystallized.
