(FL-SW) Calcite/Willemite - Franklin, New Jersey, USA

This calcite and willemite specimen is from the world-famous Franklin Mine in New Jersey, one of the most celebrated fluorescent mineral localities on Earth. Under normal light, the contrasting calcite and willemite provide an appealing texture and form. When placed under shortwave ultraviolet light, however, the specimen transforms into a dazzling display: calcite fluoresces a brilliant red, while willemite glows a vivid green. The photograph was taken under a 70W shortwave lamp to showcase the intensity of this reaction.

Franklin minerals are legendary, and their fluorescent behavior is unmatched anywhere else in the world. Collectors prize these specimens for both their aesthetic qualities and their place in the history of mineralogy. Owning a Franklin calcite-willemite piece means owning a classic cornerstone of any serious fluorescent mineral collection. This specimen is ideal for those who appreciate the interplay of science and natural beauty.
