Angel's Wing Calcite

-

In researching travertine I was led to aragonite and calcite. I came across a good list of the many varieties of calcite.

I have many different pieces of calcite from around the world that fluoresce including Nail Head Calcite from the Harz mountains in Germany, really nice Mangano Calcite especially from Peru, Dog Tooth Calcite especially from South America, and plenty of Iceland Spar from various lcations. Now I have added to my collection a large beautiful piece of Angel's Wing Calcite out of Mexico which fluoresces bright green in shortwave.
