Olivenite, Gartrellite
Cabinet, 10.0 x 7.0 x 5.0 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
This remarkable specimenis widely regarded as the best Tsumeb olivenite specimen and perhaps world's best of species, by many who have seen it in person. It is brilliantly lustrous, and pristine, and consists of huge clusters of intergrown crystals to several cm in size erupting from a light green matrix of solid Gartrellite (making this also an uncommonly rich Gartrellite specimen as a bonus). The crystals have a deep green color that comes out easily with even minimal lighting, and it just glows in person in a way not quite reflected in the picture (though I could certainly not do better, mind you, than John did!) 10 x 7 x 5 cm
