Noumas 1 Pegmatite, Northern Cape, South Africa. 50mm x 35mm x 15mm.
Cleavelandite is a variety of Albite. The Noumas 1 Pegmatite was for a very long time the largest producer of high grade feldspar hence the source of this mineral (Self collected) Our best estimate is that it has some Hyaline associated with it giving it the bright core one sees under the SW UV light.
