Owned and operated by Don and Gloria Olson, Donald K. Olson and Associates started in 1985 near Milwaukee, WI and in 1990 moved to San Diego County, California. D.K. Olson & Associates encompasses two businesses: Donald K. Olson Minerals, and Donald K. Olson Gemstones.
Both entrepreneurs, Don has been in the mineral business for over 40 years and Gloria has a Doctorate in Mineralogy from Ohio State University and has also been in the mineral and gem business for over 40 years. Don and Gloria travel across the country, buying and selling minerals, displaying at over a dozen trade shows a year with their minerals and gems at shows in California, Texas, Massachusetts, and the large wholesale and retail shows in Tucson, Arizona (February) and Denver, Colorado (September).
Don travels all over the United States, Canada and has even been to Africa and China to hand-select the rough necessary to manufacture the beautiful cabochons you see on this site. All of the slabbing (cutting the rough rock into slices) and templating (choosing the shape, design, and pattern) of the stones is carefully executed by Don and Gloria at their office and cutting facility in Southern California. The slabs are then sent to expert lapidaries (in the U.S. and overseas) and skillfully finished and polished to produce the beautiful gem cabs you see here.
Earth Traditions is proud to be a retail rep for this company, choosing some of the best of their pieces for this site. For all the jewelry designers, goldsmiths, artisans and collectors out there, please enjoy!
