What would a Langban update be without a Hausmannite, right? This is a fairly nice specimen with a large vug 3x2cm in size with numerous well-formed crystals. The neat thing about the specimn are the fantastic deep orange-red Ruchterite crystals. The largest is 3cm and is perfectly terminated. The others are much smaller but nice.
