A fine specimen of Willemite crystals accompanied by small Smithsonite crystals cover the display face of this matrix. Good form and colour make this a very desirable piece. Willemite is a rare mineral in finely crystallized specimens and there are only a few localities in the world that produce great display specimens. I think the two top localities for Willemite in the world are Franklin, New Jersey and of course, Tsumeb. The Willemite specimens from Tsumeb are highly prized for their wide range of colours and amazing beauty. Ex Thorsten Heuser collection.
