Mineral Specimen #3533    Vesuvianite Variety Idocrase with Hyaline Opal, Quartz and Calcite

Sierra de la Cruces, Coahuila, Mexico

Ex, Robert Gannon

Well formed Vesuvianite crystals which have a high luster are scattered across this specimen. The color is mostly brown but there are a couple of faces which are brownish olive green. The Vesuvianite was acid etched from enclosing Calcite some of which is still extant and is a light pinkish color. On the matrix, there is a coating of Hyaline Opal which is not noticeable until exposure to SW when it fluoresces bright green. There are several surfaces on the matrix which are covered with a druze of small squat white to clear Quartz crystals. The specimen is in fairly good condition except some of the larger crystals have incomplete damaged areas.
