N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province,
3.6 x 1.8 x 1.4 CM (small miniature/ large thumbnail (toenail))
Bright yellow crystals of the rare mineral Jourvaskite on matrix. Although small, up to just 1.5mm, these crystals are huge for the specie. Vivid color and in excellent condition. The backside of the matrix is massive Manganite with a thin layer of Rhodochrosite underlying the Jouravskite, Quartz and what seems to be Xontolite. A choice and pretty specimen of a rare mineral; ex Terry Szenics collection.
