Hambergite is a very rare beryllium borate hydroxide mineral, typically found with other beryllium-bearing species within pegmatites. Crystals are usually small, except for a small number of exceptions, one of which is the famous Stak Nala area in the Haramosh Mountains in Gilgit-Baltistan, Pakistan. This magnificent large individual crystal from Stak Nala reaches a staggering 5.3 cm in length and comes from the superb systematic collection assembled by brothers Martin and Michael Günther (1951-2007 & 1956-2021). Tabular in form, it is actually orthorhombic and white in colour like Orthoclase feldspar, but with a slightly pearlescent lustre. This is a significant, museum quality crystal of this very rare species. It is mounted on an acryllic base for display and handling.
