Description
The two rare silicates Olmiite and Bultfonteinite from the world-famous N´Chwaning II Mine of Kalahari Manganese Fields in South Africa. The Olmiite forms the typical blocky beige colored crystals while the Bultfonteinite forms snow-white sprays.The fibrous Bultfonteinite needles reach up to 4 mm, and their white color and superb pearly luster provide aesthetic and dramatic contrast with both the Olmiites and the chocolate-brown matrix . A superb combination specimen. Classic material from a find at the end of the 1990s
