Malachite - Crystals and Botryoidal forms
stock #10.1-500
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
8.3 x 6.2 x 4.3 CM (cabinet)
price: $280
Early summer 2021

A classic from Katanga, this is a two sided specimen. One side is composed of sharp radiating fibrous crystals topped by a pair of Malachite balls. The other side is all botryoidal with some distinct chatoyance caused by the balls being composed of fibrous crystals. Excellent condition, color, form and luster. The Shaba Crescent was the source of much outstanding Malachite and these are still very reasonably priced, one of the mineral world's best bargains. In person the color is a bit deeper, darker and the shimmering luster is almost impossible to appreciate in a photo.

Barite (Baryte) on Quartz
stock #6.2-178
Jinkouhe District, Leshan Prefecture
Sichuan Province, China
8.1 x 5.8 x 5.2 CM (cabinet)
price: $440
Early summer 2021

Blue blocky habit Barite crystals on snow white Quartz from older finds at Jinkouhe in Sichuan Province, China. The main crystal is fully transparent, sharp, and has faint phantoms. This is a hefty 2 CM thick and the wide faces are glassy with bright luster while the edge faces are slightly frosted. Nice contrast with the matrix and prettier in person. In very good condition there are only small minor contacts on the main crystal, the quartz is in fine condition and the smaller Barite crystal has a contact area not seen on display as well as a recrystallized edge. This is about as perfect as we can hope for and the piece displays well from most any side. These were common about 15 years ago but are now very uncommon, it seems this is no longer a producing area.

SOLD Calcite - curved saddle-form crystals
stock #SOLD 21.1-226
Herja Mine, Chiuzbala , Baia Mare
Maramures, Romania
7.7 x 4.6 x 3.7 CM (cabinet)
price: $0
Early summer 2021

Sharp edged saddle shaped crystals of Calcite with curved or bent faces in a stacked cluster. The Calcites are a flattened rhomb habit with every face showing the curved plane but most strongly visible on the largest crystals. The Calcites are a very light grey color and in good condition, some minor edge roughness exists and most of the Calcite has a matte luster on the surface that looks textured but several parts also have a brighter smooth surface as well. An odd habit that is a lot like saddle-shaped curved Dolomite but this form is not at all common in Calcite.
