USA103 - Calcite and Heulandite-Ca on Mordenite - Rats Nest Claim, Challis, Custer County, Idaho

According to John Cornish, this large cabinet specimen is one of the finest calcite specimens to come from this locality. Calcite typically forms here as a crystalline coating on mordenite. The light honey-colored calcite cluster measures 5.1 cm. It is undamaged, with some matrix attached on the reverse. The calcite fluoresces a bright cream color under both LW and SW UV. In addition, the heulandite is well-crystallized, with a zoned, light pink-orange color. 15.2 x 12.8 x 7.0 cm.
