A significant specimen of this rare, lemon yellow species from the Kalahari Manganese Fields. This major single crystal was in the collection of the legendary collector/author Ludi Von Bezing of South Africa, part of which passed to us in the very early 2000s. And then we sold it to Vasco Trancoso, where it has remained since (South Africa, to Portugal, and then to the USA). This is simply a color saturation we do not often see in nature, and it is a huge crystal as well — pics speak for the impact value!
