Dioptase
stock #21.1-192
Sanda Hills, Mindouli, Mindouli District
Pool Department, Republic of Congo (Brazzaville)
2.4 x 1.4 x .9 CM (thumbnail)
price: $490


A very bright "treelike" Dioptase thumbnail in fine condition. From the recent finds in former Brazzaville (Republic of Congo) which had produced some excellent specimens, some of which, like this one, have unusual yet eye-catching esthetics. In excellent condition, the tiny spray of Dioptase crystals on the display side are all well-terminated and undamaged. The backside has some contacts but still no damage.

HOLD Dioptase
stock #HOLD 21.1-191
Sanda Hills, Mindouli, Mindouli District
Pool Department, Republic of Congo (Brazzaville)
2.6 x 1.2 x .6 CM (thumbnail)
price: $360
Late Summer 2021

A killer thumbnail of gemmy Dioptase in elongated crystals. In perfect condition and with excellent form, this is from the recent finds in the Sanda Hills of the Republic of Congo. The Dioptase is all translucent and the termination areas are also transparent. The whole piece has a glassy-bright luster. It is hard to fully appreciate or see the rich emerald color of these crystals on a computer but the color in person is rich and saturated.

Wulfenite, very large crystal coated by Quartz druse.
stock #21.FC-003
MFouati Mine, Bouenza Department
Bouenza Department, Republic of Congo (Brazzaville)
4.7 x 3.8 x 2.2 CM (miniature)
price: $2500
Early summer 2021

A really large, sharp, fat Wulfenite crystal which is fully overgrown with a druse of sparkling Quartz crystals. This is from the first (and best) of two such finds at M'Fouti, which made big news in the mineral world. This is a superb example and a remarkable specimen from anyplace. This style and form are not known like this from any place else on earth. The Wulfenite is in perfect condition, it is broken only at the base where it was removed. There is another, perfect smaller crystal growing on one face and the orange to yellow color are more pronounced on one side of the piece, the other side is closer to a clean white hue. There were a very few pieces of this size and quality found, this is among the very best. An outstanding, unusual Wulfenite.

Wulfenite on Cerussite
stock #20-FC-059-(9164)
MFouati Mine, Bouenza Department
Bouenza Department, Republic of Congo (Brazzaville)
4.8 x 3.8 x 3.4 CM (miniature)
price: $2750
new year 2021

The new finds of Wulfenites of M'Fouati have been huge news in the mineral world. The association with Cerussite and the remarkable etching of the blocky habits is unlike any others ever found. This specimen has superb esthetics all around and is in perfect condition. The Wulfenite has intense color with glassy luster on some faces and many geometrically etched patterns on other faces. The Cerussite is complete, undamaged on all sides with just a small contacted area on the underside. These Cerussites are twinned in multiple ways and some are also etched on selective faces. There were not many specimens of this top caliber found, these few killers are instant classics.

Hydroxylpyromorphite on Cerussite
stock #20-FC-058-(9163)
MFouati Mine, Bouenza Department
Bouenza Department, Republic of Congo (Brazzaville)
5.9 x 3.1 x 1.7 CM (cabinet)
price: $2250
Spring 2020

A very fine and unusually esthetic specimen of this new and rare mineral. This is a newly recognized specie (2017) and is the Pyromorphite analogue of Hydroxylapatite (Pyromorphite is of course part of the Apatite family). The well formed Cerussite crystal is a super matrix for the white to greenish crusts of micro crystals and masses. This specimen from the Congo is by far the best looking example I have seen. It is uncommon for new or rare minerals to visible to the naked eye and less often colorful or attractive. It remains to be seen if more will be found at MFouati, it is the first find of the specie in Africa. This mineral was previously noted at three localities in Europe and two in the USA as an "unknown, undescribed" specie. In those localities this has been found only in submillimeter crystals and crusts. A superb example with a rich coverage, a superb addition for a Pyromorphite suite.

Fornacite on Dioptase (Type Locality)
stock #20-FC-115
Reneville Mine, Reneville Kindanba District
Pool Department, Republic of Congo (Brazzaville)
4 x 3.3 x 2.5 CM (miniature)
price: $1600
Spring 2020

Fantasticly rich, dense clusters of Fornacite crystals on Dioptase crystals. Fornacite is a rather rare mineral but nearly always seen just as micros with very small isolated crystals. This is an amazingly rich specimen with eye visible crystals in groups that are up to 2.5 CM across! The matrix is an attractive mix of Dioptase crystals and balls of Plancheite. The crystals are lath shaped and many are free standing, most are a dark olive green ranging to as brownish yellow with backlight. Under strong magnification a few dark green balls are seen that may be Mottramite but are not identified. From the type locality, this is a superb and important piece for this rarely displayed mineral. None of us have ever seen any piece with so much of the specie and so easily seen.
