This is a superb, exceptionally sharp twinned calcite from the famous Leiping Mine (where the more well-known V-twins were found in the late 1990s). This habit is fairly uncommon and usually the crystals are included, off-center, or otherwise marred. This piece is a perfect miniature with symmetry you could only wish for in most calcite specimens. It is gemmy and lustrous, and complete all around. This is from a famous find of the early 2000s and the style has not been seen since. These amazing, sharp "triangular " calcites are unique! And, this is a GEM example of perfect full miniature size.
