Kolwezite and Malachite after Co-rich Dolomite on Malachite and Chrysocolla after Baryte

Fluorescent light (daylight)
 

EJE73AQ0: New at Sainte-Marie 2023
A specimen that represents, apart from its evident aesthetics and its world novelty, a complete treatise on mineralogy, starting with a cobalt-bearing Dolomite (which has since disappeared during the process), followed by successive substitutions in which more copper was added, leaving as a final result Kolwezite-Malachite in pseudomorphic shapes after crystals of the initial cobalt-bearing Dolomite, and greenish blue Chrysocolla pseudomorphs after Baryte, with a stage of Malachite growth, also pseudomorphic after Baryte.
The discovery of this morphological and chemical complexity will soon be reported more extensively in an upcoming article in the French magazine Le Règne Minéral.

Olmiite

From the great Olmiite finds made in N'Chwaning Mine we offer this further material. The quality is, as you can see, much better than the Poldervaartites found in the Wessels Mine. Notably the color is much more intense and redder. On the subject of the color it is necessary to warn you that some of these new Olmiites show an intense color change depending of the kind of light used: in day light they become yellowish but in artificial light they are a spectacular strawberry red color.

Type locality




Bultfonteinite

Bultfonteinite is a rare phyllosilicate (calcium fluorsilicate) that exists in the N'Chwaning mine along with another rare phyllosilicate (also calcium), Oyelite. In fact, while awaiting the analysis of these specimens we had indicated on the web site that they were Oyelite, as previous finds from the same mine with the same appearance and white color had always been considered Oyelite. So when we got the results of the analysis, much to our surprise, the fluor present in the sample as well as the atomic ratio of Ca/Si=1:2 indicates that the specimens are Bultfonteinite and not Oyelite.

Rutile and Hematite pseudomorph after Ilmenite crystals

Very interesting novelty of 2007 Munich Show: trigonal crystals of Ilmenite transformed into an intimate intergrowth of Rutile and Hematite. Microscopic examination shows that Rutile (reddish) occurs as a delicate network of needles which are oriented parallel to the basal sections of the former Ilmenite, while Hematite (black) forms the interstices.

DESMOND SACCO COLLECTION

Desmond Sacco is an authority on African as well as worldwide minerals. I met him many years ago at the Munich Show when it was still in the center of Munich and Desmond was one of the stars of the show, buying the best that appeared. His collection was legendary, not only because of the wonders we knew he would certainly have acquired given his position in the mines of the Kalahari Manganese Field (Hotazel, Wessels, N'Chwaning...) and his proximity to the legendary Tsumeb, but also because we saw what he was buying, and thus got an idea of the quality of his collection.

Many years and many mineral Munich shows have now passed and Desmond Sacco has decided to sell some specimens from his collection. We have been fortunate to acquire an important part of this material and with these we can make a virtual trip to the mines and minerals guided by Desmond and his collecting criteria. Here we have the pieces which are still available. To see those that have already been sold you can visit the "Desmond Sacco" page in Reference Specimens

We hope you enjoy these samples, which represent an important part of mineralogy and mineral collecting in Africa.
