Questions on Moissanite & Lab Diamonds

Lab grown Diamonds are ‘real Diamonds’ and have the same physical & chemical properties. The only difference is their origin: a laboratory where they are manufactured under perfect conditions replicating the carbon process of mined diamonds.

These Diamonds are rated in the exact same way as mined Diamonds, using the four C’s method: Cut, Clarity, Colour, and Carat. View the diamond grading chart here.

Yes, lab grown Diamonds can get scratched, but it’s pretty unlikely. Like natural diamonds, lab grown Diamonds are made up of carbon atoms that give them the same hardness rating as mined diamonds (10 on the Mohs scale). This means they can only be scratched by another Diamond or a material of equal or greater hardness. While they are highly resistant to scratches, they are not entirely impervious to damage and should still be handled with care to avoid accidental damage. Certain chemical substances can tarnish lab-grown Diamonds.

These Diamonds do hold value, but this value is usually lower than that of natural Diamonds. Since lab grown Diamonds can be produced in volume in controlled environments, their supply is not limited like that of natural Diamonds, which in turn leads to lower resale prices. Lab-grown Diamond prices are also subject to market trends, usually based on supply and demand.

Lab grown Diamonds are appraised/valued using the same methods as natural Diamonds, focusing on the “Four Cs”: carat weight, cut, colour, and clarity. During the appraisal process, a gemologist will assess the diamond’s characteristics to determine its quality and, thus, its market value. Advanced tools and techniques may also be used to confirm the Diamond’s origin as lab-grown. The final price determined should reflect both the intrinsic qualities of the Diamond and current market trends.

Lab grown Diamonds can be purchased from a variety of sources, both online and in physical stores. Many well-known jewellery wholesalers & retailers offer a wide selection of lab grown Diamonds that can be customised for engagement rings, earrings, and other jewellery. When purchasing, it’s important to choose a reputable supplier, like ‘The Carbon Effect’, which provides certification from a recognised gemological laboratory to ensure the quality and authenticity of the Diamond. ‘The Carbon Effect’ is also a proud, accredited member of the Jewellery Council of South Africa.

Diamonds can be costly, but lab grown Diamonds are generally less expensive than natural Diamonds. Generally, the price is determined by the size, quality, and specific characteristics of the gem. Typically, lab grown Diamonds can cost 30-50% less than natural Diamonds, as they are cheaper to produce when compared to the costs of mining natural diamonds. While cheaper, they still maintain a high standard of quality, and they make for an attractive, more affordable option.

Yes, lab Diamonds can be certified just like natural Diamonds. These certifications assess and document the Diamond’s characteristics, including the Four Cs—carat weight, cut, colour, and clarity. These certifications also indicate that the Diamond is lab grown, which ensures transparency for buyers. A certified lab-grown Diamond provides assurance of its quality and authenticity, making it a reliable choice for consumers.
