PostPosted: Jul 01, 2018 05:07    Post subject: Phosgenite  

Another stained speciment;
I purchased it on a local mineral fair for a few bucks; the handwritten label says Phosgenite Monteponi. The crystal measures about 2.5 cm. But is is covered by another mineral.
Can it be cleaned in some way? Usually these phosgenites are transparant Crystals with a slight brownisch tint, which is probably underneath the layer.
