Time for a few minerals from Italy today. I have an amusing story about the following picture. Several years ago, on a trip to Italy, we visited Lake Como. We stayed in Baveno at a nice hotel right on the lake, and when we arrived in our room Laura opened the drapes expecting to have a nice view of the lake. She was disappointed because our room faced the other direction. I was ecstatic because we had a beautiful view of the quarry where the specimen pictured was found. We still laugh about this.

Beautiful specimens, Michael!
I love the fluorites from France and from Elmwood Mine :)
Tobi
P.S. What's the size of the gypsum from France (0507 Gypsum.jpg)?
