0.7 Carat Lab-Grown Diamonds

Carat Weight

A 0.7-carat diamond offers a stunning balance between size and affordability, making it a perfect choice for engagement rings and elegant jewelry pieces.

Lab-Grown Diamonds

Lab-grown diamonds are real diamonds created in a controlled laboratory environment rather than deep within the Earth's crust. They share the same physical, chemical, and visual properties as mined diamonds and are indistinguishable, even to a trained gemologist.

The only difference between lab-grown and mined diamonds is how they are formed. While mined diamonds develop under extreme pressure and temperature deep beneath the Earth's surface, lab-grown diamonds are produced using high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) methods in a laboratory.

Lab-grown diamonds are typically 30 to 50 percent more affordable than mined diamonds, making them an increasingly popular choice for engagement rings. This allows you to purchase a larger, high-quality diamond within your budget.

All Reve Diamonds lab-grown diamonds are certified. Most of our lab-grown diamonds are graded by IGI or GIA, two of the most reputable independent diamond grading laboratories.
