This Goboboseb Mt crystal from Namibia is one of the brightest and glassiest I’ve ever come across. It is perfectly shaped, water clear with intricate inclusions, nice wispy phantoms, and a highly movable bubble inside.
It measures 57 x 17 x 13 mm and weighs 19.2 grams. https://youtube.com/shorts/1TufYzLJRaU?feature=share
