What Is a Lab-Grown Diamond?
Lab-grown diamonds are authentic diamonds formed in controlled lab environments using advanced HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) methods. These diamonds are chemically, optically, and physically identical to natural diamonds—so much so that expert gemologists need specialized tools to differentiate them.
Lab-grown stones cost 30% to 50% less than mined equivalents and support eco-friendly, conflict-free sourcing.
Every lab-grown diamond from RÊVE Diamonds is independently certified, most often by IGI or GIA, for quality and assurance.
