"Janet & Jeff designed our wedding rings 5 years ago and I went back to them for another ring for my wife. Excellent design and excellent quality diamonds and aquamarine. They spent a lot of time working with us on the design, selection of the diamond and aquamarine. Worth every penny!" Shawn S., Tiburon, CA
