Bigrigg Calcies are world-famous, and the rabbit-ears specimens like this are highly prized: good ones rarely come available. This very good small miniature has good balance, gemmy crystals, and is in excellent condition. The luster varies from good to very good, and the largest crystal is 2.5 cm. It is actually much better in person, as sometimes the double-refraction of water clear Calcite can play havoc with the camera. It looks right through it and does not focus well! This is a little jewel. Ex. University of Manitoba.
