4JD25 - Charlesite - $ 750 SOLD
Kuruman, South West Africa
thumbnail, 3.1 x 1.9 x 1.7 cm
Sorry, we have no images of this specimen at present.

A GEMMY specimen of this rarity, which to my understanding is thought to be some kind of a mix or transition between ettringite and sturmanite (though I admit that I have heard conflicting accounts of this and some dealers DO consider it a valid species on its own merit). Either way, it is a very pretty specimen and shows crystals that are much more developed than the amorphous material you typically see. Old material, from the ettringite mining heyday of the 1980s and not to my knowledge found since

Charlesite with Ettringite - N’Chwaning II Mine, Kalahari Manganese Fields, Northern Cape Province, South Africa

Charlesite is a close relative of ettringite – and this specimen (as the Scott Williams label describes) appears to consist of (white) charlesite crystals with an outer layer of bright yellow ettringite. The crystals measure to one centimeter. You would guess the type locality for charlesite to be somewhere in the Kalahari Manganese Fields, but strangely, it is New Jersey; it wasn’t described until 1983. These crystals are nicely isolated on the dark contrasting matrix. Ex Collection of Scott Williams, also with another dealer label (priced $250).

Charlesite, Sturmanite, Calcite - N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa

Charlesite cores surrounded by sturmanite (they are a series, and portions of the crystal are of different species, thus). These crystals are unusually well-formed to be so rich in charlesite, of which they mostly are composed. Charlesite is more white or very pale yellowish white, while the sturmanite is darker in hue. 4.4 x 2.9 x 1.7 cm

Sturmanite, Charlesite - N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa

5.3 x 3.9 x 2.3 cm. Sturmanite, ettringite, and charlesite exist in a series and often in the larger crystals there is a gradient of one t the other within the same crystal. Seldom is that so obvious as here, where the colorless charlesite, which is 95% of the material and crystals present, grades to slightly yellow sturmanite at the tips of the scalloped edges. Old material from the early 1980s. Crystals to 1 cm. Ex. Charlie Key Collection.

4 x 3 x 1.7 cm. Charlesite is a close relative of sturmanite – and this specimen appears to consist of white charlesite crystals with an outer layer of bright yellow sturmanite. The crystals measure to one centimeter. Ex Scott Williams Collection.

Sturmanite, Charlesite - N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa

An EXCELLENT thumbnail of a pristine, lustrous, translucent, orange-yellow sturmanite crystal with a nicely contrasting charlesite center from the famous Nchwaning II Mine of South Africa. Charlesite and sturmanite are very closely related. 1.6 x 1.6 x 1.0 cm

Sturmanite, Ettringite, Charlesite - N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa

A SUPERB, LARGE and glassy yellow-brown crystal that exhibits all three members of the solid solution series of sturmanite, ettringite and charlesite from the famous Nchwaning II Mine. This undamaged crystal has sturmanite and charlesite on the outside and ettringite on the inside of the crystal. It has a few stepped growth elements on teh edges that show one internal member of the series, charlesite, under the sturmanite coating (those spots are not damage). The backlit photo highlights the translucency and yellow-cored interior composed of the lemon-yellow ettringite. 5.4 x 2.4 x 1.7 cm

Charlesite and Sturmanite with Calcite - N'Chwaning #2 Mine, Republic of South Africa

A very interesting specimen of charlesite cores surrounded by sturmanite (they are a series, and portions of the crystal are of different species, thus). These crystals are unusually well-formed to be so rich in charlesite, of which they mostly are composed. Charlesite is more white and lighter yellow, while the sturmanite is darker in hue as a general rule.
