Description

You are bidding on a rich thumbnail collected by Martin Jensen in 2002. A fracture surface hosts rich pale blue needles of nakauriite with dozens and dozens of sharp callagahnite crystals, large blades of hydromagnesite and a patch of tiny white dypingite crystals. Nakauriite is quite rare from this locality and the association with callaghanite is stunning with magnification.
