Why Lab Created Diamonds?
Lab created diamonds are exactly the same in chemical makeup as a diamond extracted from the earth. The only difference is that one is cultured in a lab while the other is mined from the earth. The material of diamond whether created in the earth or made in a lab, is identical. Natural diamonds are also available at Jacob Mercari.
Currently, two methods are used to grow diamonds in a laboratory: HPHT (High pressure, high Temperature) and CVD (Chemical Vapor Disposition).
Both methods start with a seed or a small piece of diamond.
HPHT employs enormous amounts of both pressure and high temperature in order to foster the growth of the diamond. Much like a diamond would grow under natural conditions in the earth.
The CVD method involves placing a seed in a contained environment adding heat and carbon-rich gases. The gases are ionized into plasma. This process is done at low pressure. This allows the molecular bonds to break in the gases and the carbon molecules to bond to the seed. In layers, the seed will grow in size.
CVD is also used to create coloured diamonds, such as rich blue and pink lab-made diamonds.
No two diamonds are manufactured exactly the same. Each one will exhibit unique characteristics and inclusions. All lab diamonds will exhibit the same imperfections and colour differences found in mined diamonds. Engineered diamonds are graded with the same 4Cs grading standard as their mined counterpart.
There is 100% absolute assurance and traceability of each diamond. We guarantee each lab grown diamond’s origin.
Yes, they are certified by GIA. The GIA offers a very detailed diamond report. The report number for each lab grown diamond is laser inscribed on the edge or girdle of the diamond for tracing and transparency. The report number can be checked by visiting the GIA website or scanning the QR code on the diamond report. The report goes deeper as well to identify three types of lab grown diamonds:
- man-made diamond produced by HPHT (High Pressure High Temperature)
- man-made diamond produced by CVD (Chemical Vapor
- Post growth colour enhanced/treated CVD grown.
This offers further transparency for the diamond buyer. They will know exactly which type of process was used to create their laboratory-grown diamond.
Manufactured diamonds are priced much more competitively compared to mined diamonds. Therefore, the cost of a lab diamond will be significantly lower than a comparable mined diamond. The price will primarily depend on the diamond’s carat, colour, clarity and cut. They have decreased in price over the last few years; it is advised not to purchase these diamonds as an appreciating asset.

- Also known as synthetic diamonds, cultured diamonds, manufactured diamonds, man-made diamonds.
- Chemically identical in makeup to mined diamonds.
- Their chemical composition is carbon.
- Both types of diamonds have a cubic crystalline structure.
- Both measure ten on the Mohs Hardness Scale.
- Light dispersion for lab-created and mined diamonds measures 0.044.
- On the Refractive Index, they both measure 2.42 and have a density of 3.52.
Whether a diamond is created in a laboratory or mined from the earth, from a scientific perspective, they are identical.
Simulants, such as cubic zirconia, moissanite, white sapphire or YAG, all score much lower for all of the above-mentioned measures. Simulants are in a different class completely. They do not have a carbon chemical composition, and the crystalline structures are vastly different. Simulants are easily distinguishable from diamonds and are not seen as a fair comparison.
Benefits of Lab-Grown Diamonds
- The Earth in Mind: Producing lab-grown diamonds results in lower carbon emissions, uses less water, and causes less earth disruption than traditional mining.
- Ethical: Lab-grown diamonds eliminate concerns about conflict diamonds, unfair labour practices, and other ethical issues associated with diamond mining.
- Affordable: Lab-grown diamonds cost less than mined diamonds of comparable size and quality, allowing buyers to opt for larger stones or higher quality within their budget.
Our lab created diamonds are available in various carat sizes, colours and clarities. We also have available fancy yellow and fancy blue diamonds.
We have lab grown diamond stud earrings in stock from 0.50ctw to 2.50ctw.
Lab-created diamond is a new and growing area of the diamond and jewellery industry. Many people are still wary as they have been bombarded with marketing from mining companies regarding the value of a naturally mined diamond for generations. We see lab-grown diamonds as the next generation and part of the evolution of the diamond industry. Man-made diamonds offer a more affordable, environmentally sustainable and socially responsible option.
Lab Created Diamond Engagement Rings
Choosing a lab-grown diamond for your custom engagement ring is a brilliant way to symbolize love in the 21st century. These diamonds provide couples a perfect blend of tradition, value, and sustainability. And with the advancements in lab-grown diamond technology, you can customize your diamond engagement ring according to colour, clarity, cut, and carat weight, just as you would with a mined diamond.
We offer free delivery across Canada via FedEx. Each delivery is insured, ensuring the safe arrival of your diamond jewelry.
Diamond jewelry can be cared for by regular cleaning with mild soap and warm water. Using a soft brush can help remove any dirt or dust. It’s also recommended to have your diamond jewelry inspected by a professional at least once a year to ensure the setting is secure.
No, you can’t tell the difference just by looking at them. They are both composed of carbon and have the same physical, chemical, and optical properties. Only specialized equipment can identify the subtle differences in trace elements and crystal growth patterns.
Yes. Because the process of creating laboratory-grown diamonds is more controllable and less resource-intensive, they can be sold at a lower price than mined diamonds without compromising quality or appearance.
Lab-grown diamonds are graded by the same criteria as mined diamonds – Cut, Color, Clarity, and Carat weight.
Absolutely! Lab grown diamond is perfect for any type of diamond jewelry, whether it’s a ring, earrings, a necklace, or a tennis bracelet. They provide all of the brilliance and sparkle of earth-mined diamonds but with a smaller environmental footprint and a lower cost.
The diamonds we sell come with a certificate from an independent lab that confirms their characteristics and verifies that it was grown in a laboratory. All diamonds sold by Jacob Mercari have a laser inscription of the corresponding diamond certificate etched onto the girdle of each diamond. Purchase from a reputable, established retailer who can provide clear information about the origin and quality of their diamonds.
