A real "monster" is this 4,8 cm measuring cluster of classic Cassiterite with an enormous 4,0 cm major crystal. The Cassi here is well developed, rich of faces and has nice brown colour. It is sharp edged as well and the display side is almost pristine, so far I can see to the naked eye. At the backside and the left side was the rock. Great and rare material is this highly impressive Saxonian piece from Zinnwald near Altenberg.
