My name is Cathy Casey and I have been specializing in rocks, minerals, fossils, meteorites, and crystals for 39 years. I am well known for my fine eye for a good specimen or beautiful piece of jewelry that I sell. I began this career in 1983 as the specimen buyer for Grieger's, Inc., one of the most well known rock shops in the United States at that time, in Pasadena, CA. I went on to serve as the twice Vice President and Program Chairman for the oldest mineralogical society in the Western United States, The Mineralogical Society of Southern California. I am very knowledgeable in this field.
