Lab-Grown Diamonds
Lab-grown diamonds are real diamonds created in a controlled laboratory environment rather than being formed deep within the Earth’s crust. They are physically, chemically, and optically identical to mined diamonds, making them an ethical and cost-effective alternative. Even expert gemologists cannot distinguish between lab-grown and earth-grown diamonds without specialized equipment.
The only difference between lab-grown and mined diamonds is their origin. While natural diamonds form under extreme pressure and heat over millions of years, lab-grown diamonds are produced using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods in a controlled setting.
Lab-grown diamonds are typically 30 to 50 percent more affordable than mined diamonds, allowing you to choose a larger stone within your budget without compromising on quality.
All Reve Diamonds’ lab-grown diamonds are independently certified, with most graded by IGI or GIA, two of the most respected diamond certification bodies.
