- Poldervaartite (From Original Find)
- Wessels Mine, Kalahari Manganese Fields, South Africa
- Miniature, 3.9 x 2.4 x 2.3 cm
- Ex. Charlie Key
This mineral was discovered in the 1980s but only recognized and named by 1993. Specimens were always extremely rare and hard to obtain. This one, Charlie was quite proud of and regarded as an important piece, worth perhaps 5k back in the day before a few years ago when Poldervaartite fortune was struck at the nearby NChwaning Mine. Literally, these were like beige gold to the collectors of Kalahari rarities! Now, OK, its a common enough species because of the new finds - BUT they are of totally different habit and these old ones are still both recognizable and desirable. This is a rare locality specimen, and probably (according to Charlie) a co-type with the material used to describe the species.
