Frequently Asked Questions

Yes. Lab-grown diamonds are real diamonds made from pure carbon and are chemically identical to natural diamonds. They share the same physical and optical properties, meaning there is no visible difference to the naked eye. Even trained jewellers require specialised equipment to distinguish lab diamonds from natural diamonds.

Lab-grown diamonds are chemically and physically identical to mined diamonds, offering the same brilliance, durability, and longevity. With a hardness rating of 10 on the Mohs scale, they are perfectly suited to everyday wear. Lab-grown diamonds are increasingly chosen for engagement rings by those seeking durability and shine -- without the exorbitant price tag.

Lab-grown diamonds sparkle at the same level as natural diamonds. Each stone is evaluated for brightness, fire, and light return to ensure exceptional optical performance. With identical physical properties and carat weight options, lab diamond engagement rings deliver the same beauty, durability, and brilliance expected in fine jewellery.

Lab-grown diamonds now account for more than half of centre stone purchases for engagement rings, reflecting a shift towards modern, considered luxury. Free from the ethical concerns associated with mined diamonds, lab-grown diamonds are 100% mine free, while delivering the same brilliance, clarity, and lasting sparkle.

Lab-grown diamonds are more affordable because they are created using advanced technology in highly controlled environments rather than being mined. They are graded by independent gemological laboratories, with GIA recognised as the global benchmark. Many buyers consider them worth buying for their consistent quality and ability to select a higher carat weight within budget.

When choosing a lab-grown diamond engagement ring, focus on cut quality, certification, and overall visual performance. Beyond the 4 Cs, each diamond should be assessed for brightness, fire, and light return. Shapes such as oval, round, emerald, and pear offer different proportions and sparkle characteristics to suit personal style.

The choice between a lab-grown diamond and a natural diamond depends on your priorities. Lab-grown diamonds offer the same beauty, durability, and wearability, while allowing greater flexibility in design and carat weight. Natural diamonds appeal to those who value rarity and traditional sourcing. Both options create a beautiful, lasting engagement ring.
