Zincite cluster (synthetic) from Poland
3 x 2.2 x 2.2 cm
Here we have a bright lemony-yellow to yellow-brown cluster of sharp Zincite crystals grown in a laboratory. Much of the Zincite that can be found on the market with claims that it all came from a collapsed smokestack in Poland is actually grown under controlled conditions in a laboratory. That being said, the material is true Zincite, and displays quite wonderfully, as shown. Note the long wave ultraviolet reaction in the bottom image! It glows a sick yellow-green to green color under the black light! Amazing!
Please note that the picture shows different views of the same specimen.
