D06-75 - Gartrellite with Olivenite - $ 475 SOLD ex. Ulrich Baumann Collection thumbnail, 2.9 x 1.9 x 1.9 cm
Found in December of 1974, this is a FINE olivenite on its own merit. The piece features a nearly gemmy crystal with great lustre, measuring almost 1 cm tall, and perched beautifully! However,the greater rarity lies in those sparkling sub-mm microcrystals at the base of the olivenite cluster. This is an extremely rich occurrence of GARTRELLITE, which is the much rarer species by far. This has been connfirmed by SEM and EDS, by the way; though the association is also indicative of gartrellite at Tsumeb. And , its beautiful!

MD-18801 - Olivenite, Gartrellite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia cabinet, 10 x 7 x 5 cm
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
MD-209732 - Olivenite, Gartrellite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia cabinet, 11.3 x 9.5 x 8.5 cm.
11.3 x 9.5 x 8.5 cm. This is an exceptionally rich specimen of the very rare mineral species gartrellite, from Tsumeb. This rare arsenate was only found sparsely at Tsumeb. This is a cabinet piece loaded with the stuff in rich pistachio green microcrystals running on and through the matrix. Brilliantly lustrous, deep green, sharp olivenite crystals provide contrast. Ex. Willy Israel and John Innes Collections.
TUC115-196 - Gartrellite - $ 1150 Tsumeb Mine, Tsumeb, Otjikoto (Oshikoto) Region, Namibia thumbnail, 2.7 x 2.0 x 1.5 cm
A rich, major specimen of the species , nearly solid with Gartrellite. Gartrellite is a mineral that was recently discovered (1990) and its presentation up until now is not that great by common aesthetic standards. Usually it is presented as dull crusts of fine-grained coatings from other locales. This is a good, showy, display-worthy specimen. Minor duftite is in association.
