Antique Engagement Rings
Our unique Diamond Concierge platform combines the high-touch engagement of a private jeweler with the ease of online shopping.
Throughout your experience with Ada, you will have timely access to your Diamond Concierge, a trained jewelry and gemology expert. Via email, phone, or video chat, your Concierge will support you along every step of the journey to fabricate a one-of-a-kind piece of brilliant art.
We believe that diamonds should not cost the Earth. Thus, we proudly offer only laboratory-grown diamonds in our fine jewelry. Ada’s sustainably cultured diamonds are diamonds, with the exact same crystal structure, chemical composition, optical properties, and physical properties as mined diamonds.
