Certified Gemologist

Owner, Ron Boyd, is recognized as a Certified Gemologist Appraiser or CGA, which is the highest title bestowed upon a jeweler. When you see a "CGA" title after a jeweler's name, it means they are an American Gem Society Certified Gemologist Appraiser. This title is the most highly regarded among peers in the jewelry industry. It certifies that this person can identify diamonds, gemstones and jewelry, and determine their value. In order to earn this title, the associate requires advanced training and experience in determining the value of diamonds and gemstones. To stay on top of their game, CGA members must pass an annual recertification exam, verifying their skill and knowledge of our industry. Ron Boyd has completed special training in Diamond Grading and Evaluation, as well as in Colored Stone Grading, Evaluation, and Identification from the Gemological Institute of America. He brings more than 50 years of experience to the store.
