If you are looking for amazing jewelry, fairly priced, offered with exceptional customer service, run, don't walk to Geoffrey's. And for some extra amazing customer service, ask for Sonny and tell her that winemaker Jon recommended her!

Geoffrey's created a stunning custom rose gold ring for me using family diamonds previous set in a necklace. They worked with me on my vision and made suggestions and improvements to achieve a final product I love. Their service is impeccable and they go above and beyond to ensure the quality of their work endures.

Yenny was an absolute angel. I ran into the store, just before closing and she was able to secure a charm for me onto a special key ring. I have used this store for years, but not in the new location. They are still a very professional team and give excellent service!! I will continue to use them for all my needs, large or small!
