“I love Jonathan K & Co.! They helped me repurpose several pieces of inherited jewelry into something I cherish and wear frequently. We also custom designed my engagement ring based on an estate ring they had, it's beautiful! Wonderful people & business, and a breath of fresh air when it came to engagement ring shopping - oh, and reasonably priced too!
If you're in Northern California, I cannot recommend them enough.”
