SOLD Malachite on Quartz with Geothite
stock #SOLD TMP-5582B
Mindingi Mine, Kambove District
Katanga (Shaba), Democratic Republic of Congo (Zaire)
8.3 x 5.5 x 3.6 CM (cabinet)
price: $0

A fine and pretty piece from a new find of botryoidal Malachite on contrasting orange-red Quartz. The Malachite balls are very well-defined and have good separation. In excellent condition, the only chipping is the outer edge where this was removed. The center of the specimen is very eye-catching hosting velvety luster green balls on bright sparkling red Quartz. It is a surprise to learn that the color of the Quartz is not due to Hematite as is normal but a much less common effect of Goethite inclusions. As far as I know this is the only example of Goethite coloring red Quartz. No matter the reason the overall effect is striking and especially nice in person.

new year 2021

A sizable mass of radiating fibrous crystals of Plancheite on matrix. The Plancheite specimens from the Congo are remarkably rich, considered by many the worlds best come from the Katanga region. This specimen is from an old find at the less well-known Mindingi Mine in Kambove. It is similar to other good specimens from the region and has the silky to chatoyant luster that is distinctive for the specie. Most often Plancheite is seen as an associate mineral, being the matrix for other Copper species, but it can be a very attractive specie in its own right. This looks especially impressive under magnification.
