Description

You won't often find an epidote from Knappenwand on matrix. You will rarely find an matrix-epidote from this location free standing. You will very rarely find a specimen like this with all indicators for quality: perfect termination, highest luster, good transparency and fine color. This specimen is really amazing, the epidote is undamaged, the base is naturally splitted in many tiny terminations.
