Lab Grown Diamonds
Learn how lab-grown diamonds are created and graded.
Discover the Future of Lab Grown Diamonds
Lab-grown diamonds are produced in controlled environments using HPHT or CVD methods. They have the same crystal structure and core physical properties as mined diamonds. Environmental and social impacts vary with the producer, energy source and manufacturing process, so compare the documentation available for each diamond.

Uncover the Sparkle of Lab Grown Diamonds
Lab-grown diamonds, also called laboratory-grown or lab-created diamonds, are produced under controlled conditions. Their carbon crystal structure gives them the same essential chemical, physical and optical properties as mined diamonds.
Why Choose Lab Grown Diamonds
Compare the cut, colour, clarity, carat weight, grading information and price of each available diamond to find an option suited to your design and requirements.
Ethical Origins
Lab-grown diamonds are created in controlled environments without diamond mining. Production methods and supply-chain practices vary, so review product-specific information when origin or sustainability criteria matter to you.
Lab Created Diamond
Lab-grown diamonds are commonly produced using High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD). Both methods create a carbon crystal structure corresponding to diamond.
Fancy Shapes
Lumex offers finely cut fancy shapes. Tireless attempts were performed to perfect size and light return ratio. Our fancy-shaped diamonds are so delegated and carefully crafted preciously so when the light reflects on the shape, they shine like a natural diamond.
Fancy Colors
Our exquisite "as grown" blues & yellows are of a similar color tone and saturation as the fancy colors found in nature. We can provide various sizes and can calibrate stones if desired.
Novelty Cut
Lumex Novelty Cuts collection offers classy and sophisticated diamond jewellery designs, Our main motive is to maintain the 4C quality of the diamond. As well as provide clarity and consistency of the cut and design, which is unique and affordable.
Durable
Are you wondering if a Lab grown diamond shines forever and durable because natural diamond is one of the toughest materials. The answer is yes, made from pure carbon, it is considered one of the strongest materials - the synonyms of toughness, durability, and resistance.
Consistent Supply
Diamond availability can vary by size, shape, colour and grade. Review the current catalogue or contact Lumex for requirements that are not shown online.
How To Create Lab Grown Diamonds

Lab-grown diamonds are produced using two principal techniques: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). The energy source, equipment and operating conditions affect the footprint of either process.
In HPHT growth, a diamond seed and carbon source are exposed to high pressure and temperature so that carbon crystallises onto the seed.
In CVD, the diamond seeds are placed in a chamber. The chamber is heated, and gas is added to the chamber. When the gas carbon atoms are broken down, they combine with a diamond seed in a form of crystal, which formation of diamond.
A lab-created diamond passing through the 4Cs of diamond same as a natural diamond. The 4C of lab grown diamonds are: Cut, Color, Clarity and Carat. Based on these four factor buyer can choose the best suits according to there needs and it in the budget.

Certification Of Lab Grown Diamonds
When a grading report is available, use it to review the laboratory's assessment of characteristics such as cut, colour, clarity and carat weight. Confirm the issuing laboratory and report details shown for the individual diamond.

IGI Certificate
The institution is a reputable entity that certifies lab grown and natural diamonds, offering detailed reports with gradings for the 4Cs, including cut, color, clarity, and carat weight.

GLA Certificate
The institution is a reputable entity that certifies both lab grown and natural diamonds, providing detailed reports, gradings, and unique identification numbers for lab grown diamonds.
