EX89Y3: Two partially doubly terminated crystals, one of them clearly dominant, isolated and with very well defined faces and edges, which is really uncommon for Minerva I Mine samples. The Witherite is on a matrix partially coated by small white Alstonite crystals.
The sample is from the Martin Zinn collection, whose label we’ll send to the buyer.
