Our Certified Gemologists

When shopping for your fine jewelry, look for jewelers who have earned the titles Registered Jeweler (RJ), Certified Gemologist (CG), or Certified Gemologist Appraiser (CGA). They are specially trained in diamond grading and/or gem identification, synthetic gemstones, known enhancements, and jewelry care. A CGA has both gemological and appraisal education and can establish values for your jewelry and obtain documentation suitable for insurance coverage.

A gem is a valuable and beautiful object fashioned from materials of nature and used primarily in jewelry. These materials are usually crystalline minerals mined from the earth. Non-crystalline minerals such as opal and obsidian, and biological materials such as amber are also used to fashion gems. The raw material, whether crystal or otherwise, is shaped and polished to bring out its inherent beauty and to render it into an attractive and usable shape. The three most important criteria of gems are that they be beautiful, rare and durable.
