There are five major clusters of this relatively rare mineral here, the one in the center having the deepest and best color. It has medium luster but what this specimen lacks in luster is made up for by the size of the clusters; to 2.4 cm across! There is some contact on one of the clusters at the periphery on the bottom, but overall the specimen is in fine shape and presents very nicely with good 3-dimensionality. N'Chwaning poldervaartites are of course HIGHLY sought-after specimens! 6.8 x 4 x 2.5 cm
