SHIGAITE on RHODOCHROSITE from N'Chwaning II Mine, Kalahari Manganese Fields, Northern Cape Province, South Africa [db_pics/pics/cktsr-4a.jpg]

A beautiful specimen, complete 360 degrees, hosting a translucent 2 cm shigaite perched on sparkly rhodo crystals! This is a piece of major importance in the world of rarities, and Charlie felt that for combination of size and aesthetics it was the best miniature from the find of the early 1980s that he could keep in his suite of personal Kalahari rarities of miniature size - this was in fact the pride of the collection, I'd say. it is NOT the fragile, thin, disclike crystal you expect to see form looking at the recently mined material. it is very thick, sturdy, and easily packed for shipping. Although a "toenail" size, it is important enough to take its place in a miiatures or rarities suite of stature, and is really irreplaceable.

Shigaite, Rhodochrosite from Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa [db_pics/mdpics/MD-114276a.jpg]

3.5 x 1.8 x 1.0 cm. A SUPER SHOWY and UNUSUAL combo piece from the Wessels Mine of TWO colors of shigaite perched atop a field of rose-red, gemmy rhodochrosite crystals. A highly lustrous, cherry red shigaite crystal sits at the base of the very flashy golden shigaite crystal "feather." This is a STRIKING cutie, where the overall visual impact is not impaired by the cleavage on the "feather" and the modest periphery damage on the rhodos. Shigaite is VERY RARE and the association with rhodochrosite in this piece, makes for an aesthetic treat.

9.1 x 6 x 3.5 cm. This piece features a superb .7cm Shigaite crystal with classic iridescent yellow-to-red color and incredible luster. It guards the gate into the pocket of gloriously sparkling rhodo behind it! Scattered in the beautiful Rhodochrosite pocket are numerous smaller hexagonal blades of shigaite that are gemmy red.

4.3 x 3.3 x 1.5 cm. A beautiful and excellent combination specimen of a solid crust of very sparkly, transparent, rose-red rhodochrosite crystals RICHLY covered with gemmy, cherry-red, micro shigaite crystals on matrix from the famous N’Chwaning II Mine. This piece comes from a small recent find and is exceptional material with the extensive shigaite coverage.

Rhodochrosite, Shigaite from N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa [db_pics/mdpics/MD-120833b.jpg]

12.2 x 11 x 10 cm. A visually very impressive pocket of sparkly balls of drusy Rhodochrosite covered with Shigaites. The largest of the balls is almost 2 cm across, and they all display quite well in the exposed pocket. Of great interest is the fact that the Rhodochrosite is populated with what must be a hundred Shigaite crystals about 1mm in size. Interestingly, these Shigaite crystals are more prismatic in habit rather than the hexagonal blades.

This piece comes from a small recent find and is highly representative of both species.

Shigaite, Rhodochrosite from N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa [db_pics/mdpics/MD-160204b.jpg]

10.0 x 7.8 x 6.0 cm. This specimen has dark red crystals of the rare manganese species shigaite, ensconced on attractive, sparkling manganite blades and accented by rhodochrosite. It is from a small 1993 pocket and is said to be one of the best of that pocket. It was sold to John Barlow soon after by Charlie Key. An important specimen, this piece at one time was considered one of the world's great specimens for the species and resided in a pre-eminent collection of such rarities (John Barlow's). It still is significant, though others have been found recently of a different style. The new ones are more gracile and fragile-looking but have a metallic lustre and brighter color, whereas these crystals are more robust and dark. Also this matrix association is unique to the 1993 pocket which really did redefine the species in terms of quality. Illustrated in the F. John Barlow Collection book, in his chapter on South Africa.

6 x 3.4 x 2.2 cm. TWO sharp, metallic, beautiful shigaite crystals are dramatically displayed here…they are literally metallic in lustre, and this locality has produced the worlds best of species by far for the reasons of sheer beauty and size. The crystals are about 6 and 4mm. They are perched on sparkling, fake-looking rhodochrosite matrix that itself is so shiny and lustrous that it is nearly metallic in lustre. Overall a beautiful plate and a stunning specimen. Ex. Charlie Key.
