  • "I had the best experience working with Joanna. I contacted her about making a custom tooth necklace for me. The whole process was amazing and the end product turned out perfect. I would highly recommend choosing her to work with for your custom jewelry needs."


  • "I was referred to Joanna through a family member when my partner and I began engagement ring shopping. We decided to design a custom ring, and Joanna walked us through every step of the process! She was thoughtful, patient, knowledgeable, and completely transparent. I couldn't be happier with my ring and with our overall experience."


  • "The most gorgeous rose cut diamond, opal and ruby ring. Joanna’s designs are unique, modern with an antique sensibility and always elegant and beautiful. The craftsmanship on the ring is flawless."
