Do you specialize in a particular area? If so, please tell us about your specialty.

Over 25 years as a Graduate Gemologist. My main roles at Jeweler's Touch have been Diamond Buyer, Jewelry Appraiser, and Marketing. I specialize in gem identification, diamond grading, and jewelry valuation. I have advanced training in laboratory grown diamonds, identifying gemstone treatments, antique & period jewelry, personal property valuations, personal property research & analysis, and retail replacement appraisals.

How did you get started in the jewelry industry?

My brother & sister-in-law own Jeweler's Touch. I was in a completely different industry but would visit the store often. I fell in love with the positive culture at Jeweler's Touch and wanted to be a part of it.

What do you love most about working in the jewelry industry?

During the jewelry appraisal process, every time a client would hand me their jewelry, they would tell me the story of how they got that piece of jewelry. It was inherited from grandma, it was a graduation gift, their first Mother's Day gift, or a self-purchase for a big promotion at work. The stories were endless. I loved hearing the stories while I appraised jewelry and being a part of creating those stories as a diamond buyer.
