Sturmanite - large stacked crystals
N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province,
7.4 x 4.7 x 3 CM (cabinet)
New Year 22
Very large and well-defined cluster of Sturmanite crystals with a patina that in some light shows a iridescent color play. Not long ago Sturmanite was a very rare mineral and such huge crystals were unheard of. The great finds from South Africa changed that, but this size and level of quality is still very uncommon. Very impressive in person and now very hard to get.
