About Me

As a Graduate Gemologist from the Gemological Institute of America and a Certified Master Appraiser with the National Association of Jewelry Appraisers, I bring the training, experience, and professional judgment needed to accurately identify, grade, and value diamonds, gemstones, and fine jewelry. With nearly 38 years in the jewelry industry—including more than 35 years specializing in jewelry and gemstone appraisals—I understand jewelry from every angle. My experience in jewelry repair, design, and fabrication allows me to evaluate not only the gemstones, but also the craftsmanship, condition, construction, and overall quality of each piece. I appraise approximately 400 pieces each month, ranging from individual jewelry items to complete estates. Every appraisal is completed with careful research and attention to detail, providing you with an accurate and reliable replacement value for insurance, estate planning, resale, or personal documentation.

Custom Jewelry

With 38 years of experience in the jewelry industry, I bring a deep understanding of gemstones, precious metals, craftsmanship, and design to every piece I create. When I am not appraising jewelry, I enjoy designing and handcrafting custom pieces that reflect each client’s personal style and story. My goal is to create jewelry that feels distinctive and meaningful while maintaining a timeless design that can be enjoyed and passed down for generations.
