In Bulgaria also there are very beautiful calcites. This is my recent find - calcite druse and single crystals. They are from Sliven, but the most interesting crystals are found in the Eastern Rhodopes and Burgas.

I just read the LAPIS extra issue about calcite (from 1998) which features a "top ten" ranking of calcite localities. The experienced mineral experts Helmut Brückner, Dr. Ulrich Burchard, Herb Obboda, Christian Weise, Dr. Hans-Jürgen Wilke, Victor Yount and Walter Hess were asked which they would call the "top ten". According to their answers, this was the ranking (don't forget it was made 20 years ago, so no wonder that there are no certain Chinese mines, only "China". Also, the list only says "India" and "Mexico" without any details):
1. Cumberland, UK
2. Tennessee, U.S.
3. Sankt Andreasberg, Harz Mts., Germany
4. Dal'negorsk, Russia
5. Mexico
6. Tsumeb, Namibia
7. India
8. China
9. Erzgebirge, Saxony, Germany
10. Michigan, U.S.
