What Is a Lab-Grown Diamond?
Lab-grown diamonds are real diamonds created in a laboratory setting, using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) process. They are physically, chemically, and visually the same as mined diamonds—so much so that even expert gemologists require advanced equipment to tell them apart.
Choosing lab-grown means saving 30% to 50% over the price of a natural diamond, all while making an environmentally conscious and ethical decision.
All REVE Diamonds’ lab-grown stones are independently certified, most commonly by IGI or GIA.
