Item Description
Portlandite is a rare Calcium Hydroxide that occurs very seldom in nature. There are dozens of bone-white Portlandite blades up to 4 mm covering about half the matrix, and it is intergrown with clear Quartz crystals. A good specimen of a rare species, from the well-known Wessels Mine.
