Diamond Nexus Labs: A lab-created diamond simulant must function exactly like an earth-mined diamond. It has to sparkle, cut glass, dazzle you with its radiance and keep the secret of its origin so that everyone who sees it believes it to be real. That beautiful, flawless jewel must then be regally placed in a setting so perfect in its detail and graceful in its design that even the most discriminating jewelry connoisseur would be proud to own it.
