4 Carat Lab-Grown Diamonds
Carat Weight
A 4-carat diamond makes an exceptional statement piece, perfect for engagement rings and other fine jewellery.
Lab-Grown Diamonds
Lab-grown diamonds are real diamonds created in a laboratory rather than deep within the Earth's crust. They are physically, chemically, and visually identical to earth-grown diamonds and indistinguishable, even to a trained gemologist.
The only difference between lab-grown and earth-grown diamonds is their origin. Earth-grown diamonds form under extreme pressure and temperature beneath the Earth's surface, whereas lab-grown diamonds are created under high pressure and temperature (HPHT) in a controlled laboratory environment.
Lab-grown diamonds are typically 30 to 50 per cent more affordable than earth-grown diamonds. This makes them a popular choice for engagement rings, allowing you to select a larger diamond within your budget.
All Reve Diamonds lab-grown diamonds are certified. Most of our lab-grown diamonds are certified by IGI or GIA, the most respected independent diamond grading laboratories.
