Okenite, Calcite, Gyrolite on Quartz
Location: Pune (Poonah), Maharashtra, India
Size: 140x165x73 mm (1794 gr.)
A very large specimen featuring numerous puffballs of acicular crystals of Okenite with balls of gyrolite on a heavy grey basalt coated with white Quartz microcrystals. This one is special because it has two nice twin crystals of caltcite, with dark phantoms inside.
Some needles of the okenite balls are broken.

My father (Gunnar Mathisen) bought this one together with other Indian minerals, directly from India in the late 1980's.
