Creedite

Creedites come in a range of colors and are most common in colorless or orange. The most desireable are the purple ones more recently found in China but also found at West Camp in the 1970’s. According to Moore’s Compendium the last of the purples came out in 1984. The largest individual crystals rarely exceeded 2cm. This specimen hosts an individual crystal reaching 1.7cm with many at or over 1cm. The color is a pale amethystine. Original pricing on the older Fender Minerals label is $595. His labels have the locality as Santo Domingo Mine on one and West Camp Mine on the other, but I believe it is either the Inglaterra or the Potosi Mine, which were connected at West Camp.
