Description

This is a quality specimen of the famous pseudomorphs of chrysocolla after baryte. I've seen some specimens from this location, but this quality is exceptional. The specimen is in good condition. The form of the older baryte is very well visible, even if it's completly morphed to chrysocolla. Have a look at the incredible structure, just eye-candy.
