All Trilogy Rings

Superior Beauty

Lab-grown diamonds have been successfully produced for decades by manufacturing the exact conditions under which mined diamonds are formed.

Everything from the look, feel, weight and chemical makeup to the sparkle and light refraction are exactly the same as an earth grown diamond. Lab grown diamonds have matured not only to meet their mined counterpart in every way, but even surpass the quality of a mined diamond.

Quality Driven

Mined diamonds are at the mercy of the elements over hundreds of years, therefore often have a yellow discolouration and heavy inclusions, which in turn results in low clarity and sparkle. Laboratory diamonds on the other hand, though the process of creating them is very complex, are more consistent in quality (colour, clarity, cut, carat) as the environmental factors that they are formed under are able to be contained, which results in less waste with over 90% of lab grown diamonds going on to be set into engagement rings.

Lab Diamond FAQs

Yes! Lab grown diamonds are just as real as natural diamonds.

With the exact same optical, chemical, thermal and physical properties, the only difference between lab diamonds and natural diamonds is their origin. Lab diamonds are grown in controlled laboratory environments that simulate the same conditions and pressure that grow natural diamonds in the earth.
Lab grown diamonds are completely different to diamond simulants. Simulant diamonds are manufactured tolook likea real diamond, but are made from totally different materials. The most well-known simulant is cubic zirconia (CZ) which is a crystal form of zirconium oxide. Lab grown diamonds are made from actual carbon atoms arranged in the characteristic diamond crystal structure - making them 100% real diamonds!
A lab grown diamond has the same chemical and physical properties as a diamond while a simulant is made of a different material, designed to simply mimic the appearance of a diamond. One of the most well-known simulants is cubic zirconia and is made from a soft substance called zirconium dioxide. Simulant diamonds will not have the same longevity as real diamonds and will need to be replaced every few years. Lab grown diamonds are exactly the same as natural diamonds, made of pure carbon and with a hardness rating of 10 on the Mohs hardness scale. A lab diamond will last just as long as a natural diamond.
The only difference between a natural diamond and a lab diamond is their origin. Natural diamonds are formed in the Earth’s crust under intense heat and pressure and then mined from the ground. Lab diamonds are grown under the exact same conditions as natural diamonds but within a laboratory setting - removing the need for mining. With the exact same chemical, physical and optical properties, the only real difference is that natural diamonds are mined and lab grown diamonds are not. This makes lab diamonds the ethical, eco-friendly and sustainable choice.
Lab grown diamonds are an excellent alternative to natural diamonds as they provide much more value. Without sacrificing quality for price, lab diamonds will be more affordable than natural diamonds of similar quality and size.
