Description

You are bidding on a small sample with a trully strange and interesting growth of titanite. A very long, winding and twisted titanite crystal lays on the matrix with other titanite crystals, epidote lathes, natrolite prisms and complicated calcite and analcime crystals. Must be seen to be fully appreciated for how unusual the titanite is here. Collected by Don Owens in 1989.
