Schorl crystals on Feldspar from the Erongo Mountains in Namibia. Partly UV-active. One unique flat for mineral collectors.
This unique flat contains a varied selection of Schorl crystals on Feldspar from the Erongo Mountains of Namibia. The deep black, lustrous Schorl crystals contrast beautifully with the light coloured Feldspar and display a range of crystal habits and sizes. Some specimens in this flat are partly UV-active due to fluorescent areas within the Feldspar. The flat shown is exactly the collection offered.
Geology & Origin
The Erongo Mountains in Namibia are among the world's most famous localities for pegmatite minerals. Within these granitic pegmatites, Schorl, Feldspar, Quartz and numerous other mineral species crystallized over millions of years. The combination of well-formed Schorl crystals and light coloured Feldspar has made this locality highly sought after by mineral collectors around the world.
