Yes! Lab grown diamonds, also known as laboratory grown diamonds or ethical lab grown diamonds, are chemically identical to mined diamonds or natural diamonds. They offer the same level of beauty and are an extremely popular choice

A lab grown diamond, unlike a simulant, has the same chemical and physical properties as a mined diamond. They are aesthetically identical to naturally mined diamonds, offering the same fire and brilliance.

The only difference between a mined diamond and a lab grown diamond is their origin. Lab grown diamonds are an ethical and sustainable option, offering the same fire, clarity, and carat weights as mined diamonds.

Lab grown diamonds are a sustainable option, created using advanced technology under high pressure, which is much more ethical than traditional diamond mining methods.

We specialise in lab grown diamond Jewellery. Our collection, available to shop online, ranges in carat weight and design, ensuring you find the perfect diamond Jewellery for your needs.

Lab grown diamonds are an excellent alternative to mined diamonds as they provide much more value. Without sacrificing quality for price, lab grown diamonds will be more affordable than mined diamonds of the same quality and size.

Just like mined diamonds, lab-grown diamonds are unique and can have minor imperfections. While each diamond varies in color, clarity, and cut, we carefully select only the best diamonds we produce.

Our expert craftsmanship ensures the highest quality and optimal light reflection, eliminating the need for extensive diamond knowledge. You can trust that you're getting a beautiful, high-quality diamond without the need for a "PhD in diamonds."

Absolutely not! Since lab grown diamonds have the exact same physical and chemical properties as mined diamonds, they are just as durable and scratch-resistant, meaning they will never become cloudy.

Since the late 19th century, scientists have strived to recreate diamonds in a laboratory setting. While General Electric achieved the first successful large-scale production of lab-grown diamonds in the 1950s, these initial diamonds were primarily intended for industrial applications and lacked the quality necessary for jewellery. It wasn't until the late 1980s that gem-quality lab-grown diamonds became commercially available, offering consumers an alternative to mined diamonds.

Yes, lab grown diamonds will pass a diamond tester. Since lab grown diamonds are made of pure carbon and have the same thermal conductivity and chemical properties as real diamonds, they will record a positive test on a diamond tester.

To ensure consistency of certification, every lab created diamond is inspected and certified by a gemological expert at the IGI. Using a very fine and precise laser beam, every lab grown diamond is inscribed with the report number and the words “lab grown”, assuring you of your diamond’s origin and authentic certification. This inscription is invisible to the naked eye and can only be seen under a jeweller’s loupe. In no way will this impact your diamond’s quality or light performance.

Absolutely! All of our lab grown diamonds are evaluated on cut, clarity, colour and carat weight and are IGI or GIA certified. Most of our lab grown diamonds are certified by the leading lab grown gemological institute, IGI. The IGI is the most popular lab-created diamond certifier and is used by most of the lab market, creating a consistency in grading across the lab grown diamond industry. This allows the consumers to easily compare lab grown diamonds and to be assured they’re getting what they’re paying for.

Lab grown diamonds are produced in controlled laboratory environments and do not need to be mined from the earth. Unlike mined diamonds, only lab created diamonds can be 100% conflict-free. It is near impossible to know the origins of a mined diamond and whether unsafe or unethical labour practices were involved in its extraction from the earth.

Lab-grown diamonds offer an eco-friendly alternative to mined diamonds, significantly reducing environmental impact. The mining process for a single carat of mined diamond requires the extraction of over 250 tons of ore, causing extensive damage to ecosystems and displacing wildlife. Lab-grown diamonds eliminate this need, ensuring the preservation of natural habitats, wildlife, and ancestral communities.

While we offer lab-grown diamonds as a sustainable option, we also carry a curated selection of ethically sourced, pre-owned mined diamonds. These diamonds have lived a life before, contributing to a circular economy while minimising the environmental impact of new mining

At Luma Jewellery, we understand that your love story deserves a ring as extraordinary as your commitment. We meticulously craft each lab-grown diamond ring with the same passion and artistry that has defined luxury for centuries.

Our lab-grown diamonds are not merely an alternative, they are a revelation. They possess the same captivating fire, brilliance, and sparkle as their mined counterparts, yet are born from the cutting edge of scientific innovation. These exquisite gems are grown in meticulously controlled labs, replicating the earth’s extreme pressure and temperatures. While trace elements might vary, the result is a diamond that is indistinguishable in its beauty and brilliance.

Why choose Luma? Because our lab-grown diamonds embody the very essence of modern luxury:
