The classic one carat diamond engagement ring has a timeless elegance that lasts for generations. At RockHer, we make one carat diamond engagement rings every day but each ring we make is one of a kind, made to order to fit a specific diamond and a specific woman. The perfect one-carat engagement ring begins with the perfect diamond: individually selected for its beauty and lasting value with the assistance of ROSI, our AI diamond-picking algorithm powered by IBM’s Watson. ROSI searches through all the one-carat diamonds available on the market to find the best balance of quality and value, weighing more than 20 individual quality characteristics. Then we create the engagement ring from scratch, just for you, in your choice of recycled gold or platinum. Your bespoke ring is designed and crafted in California with lasting quality to be a symbol of your love forever.
