A novelty of Munich 2008. The sample forms globular growths of well defined terminations of crystals. The deeper color is similar to the older pieces, classified then as Poldervaartite.

Olmiite.
EQ6E8: Olmiite
Two complex crystals placed on their matrix to give a very aerial sample. It stands out for the sharpness of the crystal form, which is prismatic and double–pyramid, which is not that common in Kuruman. While the color is a little less intense than other samples it is compensated for by the intense brilliance, which is due to the large number of flat faces on the crystals.

Olmiite.
EB54E8: Olmiite
This one stands out for the crystalline terminations, pyramidal and in complex groups that give it a spherical look, and the sharpness of the forms of the prismatic faces. Both the color and brilliance are magnificent. The position of the group on the matrix makes it very esthetic and adds the definitive touch.

Olmiite.
EB2B9: Olmiite
Two photos showing its spectacular color change. Just minor matrix on its rear, almost a floater specimen complete in all sides with perfect form and excellent luster-color perfection. The crystals have a spherical form, they are gemmy and are formed by hundreds of small parallel grow crystals. A beauty!.
This specimen was photographed for the magazine ‘Mineralien Welt’ and appears on page 18 of number 1/2009.

Olmiite with Calcite.
TM98D8: Olmiite with Calcite
Recently new Olmiites were found in N'chwaning. The color is a little more orange than the first ones, and the crystals are a little bit smaller. But these ones are on a matrix of small crystals of gemmy Calcite, making the whole specimen esthetically pleasing. The prices are also lower than they were for the first ones, so we think they are a good deal. In this case the crystals of Poldervaarite are well positioned on the matrix, nicely separated, aerial, and have good contrast with the matrix.
N'Chwaning II Mine, N'Chwaning mining area, Kuruman, Kalahari manganese field (KMF), Northern Cape Province  South Africa (11/2003)
Specimen size: 8.2 × 6.3 × 2.2 cm = 3.2” × 2.5” × 0.9”

Price: [SOLD]
Olmiite with Calcite.
MX56V7: Olmiite with Calcite
Bundled aggregates of Olmiite crystals with slightly curved faces and edges, good color and excellent luster, on matrix and on a base of scalenohedral Calcite crystals. The sample is from the Desmond Sacco collection whose label we’ll send to the buyer.
N'Chwaning II Mine, upper levels, Kuruman, Kalahari manganese fields, Northern Cape  South Africa (±2008)
Specimen size: 5.5 × 4.4 × 3.4 cm = 2.2” × 1.7” × 1.3”

Price: Euro:170 / US$201 / Yen:22630 / AUD$250
Olmiite with Calcite.
TM96N2: Olmiite with Calcite
A novelty of Tucson 2009. Unusual groups of crystals of irregular contour, more or less oval-shaped. They are pink, and more intense on the terminations. They are on very acute scalenohedrons of Calcite and on matrix. They have come from a single geode. At first we believed they could be Poldervaartite due to the presence of the accompanying Calcite and the pinkish color of the crystals, but the analysis confirms that they are Olmiite (the manganoan end of the series) and not Poldervaartite (the calcian end). We’ll send a copy of the analysis to the buyer of the sample.
The specimen has been reviewed, photographed and published as a new discovery in the magazine ‘Mineral Up’ on page 29 in number 2009/2.
