Description

Double-terminated bustamite crystals on and partly in matrix, showing salmon-brown color & good luster.
I missed to photograph the (very good) little spessartine crystals at the foot of the longest bustamite crystal.
The longest bustamite crystal measures 2.9 cm, the thickest - vanishing into the matrix - has a diameter of 1.3 cm.
The black spots are sphalerite crystals on the big one and minor galena at the side of the other.
