About 1 Carat Lab Grown Diamonds
1 Carat Lab Grown Diamonds – Brilliant, Modern, High-Value Luxury
A 1 carat lab grown diamond is one of the most sought-after choices in the United Kingdom, offering the ideal balance of size, brilliance and value. Created using advanced CVD and HPHT technology, these diamonds share the exact same carbon structure, hardness and optical beauty as mined diamonds — with a responsible, above-ground origin. Their purity, sparkle and modern sustainability make them an exceptional choice for engagement rings, pendants, earrings and bespoke fine jewellery.
At Variation, each 1 carat lab grown diamond is hand-selected for brilliance, symmetry and precision. With IGI-certified grading and refined craftsmanship, our diamonds provide premium quality for UK customers seeking elegance, transparency and real value.
What Is a 1 Carat Lab Grown Diamond?
A 1 carat diamond weighs 0.2 grams but delivers impressive visual presence, making it the most popular carat weight for fine jewellery. Lab grown diamonds follow the same crystallisation process as natural diamonds, produced in controlled environments that replicate the Earth’s diamond-forming conditions. This allows them to match mined diamonds in beauty and performance while offering sustainable and ethical advantages.
