Sean personally sources and grades every diamond MYD sells, and leads the brand's client consultations and direction. The rings themselves are hand-finished by MYD's master jeweller, an experienced craftsman with 20+ years of bench experience who works in our Sydney workshop. The master jeweller has asked not to be named publicly and prefers to let the work speak for itself. Together, this dual structure, credentialled gemmologist founder plus private master craftsman, is a classic luxury atelier arrangement.
