A 7-carat diamond is a luxurious and eye-catching choice, perfect for engagement rings, necklaces, or high-end jewellery pieces. It is an impressive size that radiates elegance and prestige.
Lab-grown diamonds are real diamonds created in a controlled laboratory rather than forming deep within the Earth's crust. They are physically, chemically, and visually identical to mined diamonds and cannot be distinguished, even by a trained gemologist.
The only difference between lab-grown and mined diamonds is their formation. Mined diamonds develop under extreme pressure and temperature deep within the Earth, while lab-grown diamonds are produced using high pressure and temperature (HPHT) or chemical vapour deposition (CVD) in a controlled setting.
Lab-grown diamonds are typically 30 to 50 percent more affordable than mined diamonds, making them a popular option for those seeking a larger, high-quality diamond within their budget.
All Reve Diamonds lab-grown diamonds are certified by leading independent diamond grading laboratories such as IGI or GIA.
