Lab Grown Diamonds
Why Lab Grown 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.
At present, there are two methods used to grow diamonds in a laboratory: HPHT (High pressure, high Temperature) and CVD (Chemical Vapor Disposition).
Both methods start with a seed or 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 grown 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 colored 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 created 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, lab grown diamonds 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 diamond:
- man-made diamond produced by HPHT (High Pressure High Temperature)
- man-made diamond produced by CVD (Chemical Vapor
Deposition) - Post growth color enhanced/treated CVD grown with one/few processes.
This offers further transparency for the diamond buyer. They will know exactly which type of process was used to create their laboratory-grown diamond.
Each man-made diamond is certified by a trained gemologist. We provide a full grading certificate from GIA, IGI or GCAL.
Manufactured diamonds are priced much more competitively compared to mined diamonds. Therefore, the cost of a lab diamond will be significantly higher than a comparable mined diamond. The price will primarily depend on the diamond’s carat, colour, clarity and cut. Lab Grown Diamonds 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 or lab created 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 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 lab 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 measures mentioned above. 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 diamond and are not seen as a fair comparison.
Our lab created diamonds are available in a variety of carat sizes, colours and clarities. We also have available fancy yellow and fancy blue diamonds. However, availability is minimal, so please make sure to book an appointment before coming in.
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 natural 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.
Our lab grown diamonds generally range in price from $500 to $25,000 and above, depending on the carat size, colour and desired clarity. Please get in touch with us for a more precise quotation.
