Round diamond engagement ring featuring double-helix

$2,575

Please complete all fields.

Natural Diamonds are sourced from mines using traditional methods while Lab Diamonds are grown from a seed under conditions that replicate the underground creation process. Both are physically, chemically, and optically the same. Our mined diamonds are certified to be Kimberly Process compliant and conflict free, while our created diamonds are renewable and come from a guaranteed origin.

Our client wanted his partner's passions exhibited somehow in the ring he would use to promise himself to her for the rest of his life.  We came up with the idea of incorporating a double helix because she is a genetic scientist -VOILA!
