Mayson by Sethi Couture is designed by Prerna Sethi, sister of Sethi Couture designer Pratima Sethi. The name alludes to stone builders, or masons, owing to this collection's architectural iconography. "I was a student of architecture and continue to derive influence from great works including Le Corbusier and Shigeru Ban. I wanted to keep the aesthetic more contemporary....making the gemstones the focal point." The blackened silver and 14k yellow and rose-gold accented pieces by Mayson feature diamonds, garnets, peridots, sapphires, moonstones, and more. Mayson is based in San Francisco, CA.
