Lab grown diamonds offer an ethical and cost-effective alternative to traditional mined diamonds. Laboratory-grown diamonds are made in a lab by emulating the forces and conditions that exist in the earth to form natural diamonds. Man made diamonds are made using pure carbon and share the exact chemical properties of natural diamonds.

On average, our range of lab grown diamonds are around 75% cheaper than an equivalent mined diamond. They are visually, physically, and chemically the same as traditional diamonds. Our range of lab grown jewellery includes lab grown engagement rings, lab grown tennis bracelets, lab grown diamond earrings, and loose lab diamonds. Just like our natural diamond collection, you can customise our laboratory collection to suit your exact requirements across thousands of pieces of jewellery.

Frequently Asked Questions

Is a lab grown diamond a real diamond?

In a word, yes. A lab grown diamond is made of exactly the same material (carbon) as a ‘real’ mined diamond. Although a lab grown diamond is made in a lab, it is still subjected to the same process a earth mined diamond goes through but in a speed up and controlled environment. The only difference between a natural diamond and a lab grown one is the how it was sourced, they are the same in every other way. 

To add to their credibility, lab diamonds are also certified by the International Gemological Institute (IGI) ensuring their quality and authenticity as real diamonds.

How much do lab diamonds cost?

Lab grown diamonds can cost 75% less than mined diamonds. For instance, a 1.00CT D VS1 lab-grown diamond in Sydney might cost around $1,089, whereas a natural diamond with the same specifications could cost over $4,000.

Buyers have the opportunity to obtain a larger and higher-quality stone at the same price point, which is one of the biggest reasons why lab grown diamonds have become an increasingly popular choice.

How long do lab grown diamonds last? 

Lab grown diamonds have the same lifespan as natural diamonds, and if looked after properly will last forever. A diamond is an extremely strong material; it sits at the top spot on the MOHs scale of hardness as a number 10. Make sure to get your diamond jewellery professionally cleaned every year to keep it in the best condition. 

Can you tell if a diamond is lab grown?

Lab grown diamonds will look identical to a mined diamond after they have been cut and polished. To the human eye there would be no difference, made of the same material the only way to tell the diamonds apart is with a gemologist. A gemologist is a trained professional who with the right equipment can see the diamonds fluorescence patterns which differ in lab diamonds. 

You don’t have to worry about anyone spotting the difference if you buy a lab grown diamond ring, they are still as exquisite and stunning as a natural diamond. 

Are lab grown diamonds better for the environment? 

Compared to mined diamonds, lab grown diamonds are better for the environment. Diamonds that are mined create a substantial amount of carbon emissions and use a high quantity of electricity. Lab grown diamonds don’t use any harmful chemicals in their production and only use a modest amount of electricity.

How are lab grown diamonds certified? 

Lab grown diamonds are certified through GIA certification. In order to be certified, diamonds must go through a rigorous testing process to ensure it meets the strict requirements of GIA. GIA has only recently begun to certify lab grown diamonds in the same way that natural diamonds are certified. Previously, lab grown diamonds were only ever certified by grading categories. That being said, lab grown diamonds will be graded differently to mined diamonds. This is because there can be subtle differences between the two, such as slight variations in colour or clarity. These variations are not detectable to the naked eye but may affect the grading of the diamond.
