Each Couplet piece is handmade to order by craftsmen and artisans in New York City. All of our gemstones are ethically sourced. We're proud to partner directly with mines to ensure safe and humane practices throughout the gem discovery and cutting processes.
In the English language, the word "couplet" refers to a pair of lines in poetry, however this was adapted from the French "couplet," meaning two pieces of metal welded or hinged together. One word that combines our love for poetry, couples, and metal smithing? It us.
Our founder, Sophie Smith Quinn has been a jewelry addict as long as she can remember. On more than one occasion growing up she was caught red handed in her mother's jewelry box with rings on every finger. To this day, her mother's style remains one of Sophie's greatest inspirations. When Sophie moved to New York to work in the fashion industry, she would find herself in the diamond district to make custom gifts for her mother and sister. People then started asking to buy the pieces she was designing as gifts. The next thing she knew, Couplet was born.
