Diamonds of laboratory origin are genuine diamonds

Almost none. Lab grown diamonds exhibit the same physical, chemical and optical properties as natural diamonds – it is impossible to distinguish them from natural diamonds with the naked eye. Specialized equipment is required for identification. However, the environmental and sustainability aspects of lab-grown diamonds deserve mention. Laboratory synthesis is much more targeted; only a fraction of the diamonds obtained during extraction are of a quality suitable for jewellery. In the laboratory, however, the quality of the resulting stones can be greatly influenced.

Yes. Lab-created diamonds can cost 60-80% less than a natural diamond of similar size, colour and clarity. Prices for larger carat lab diamonds are dropping significantly faster than prices for smaller carat weights.

Lab grown diamonds have the same quality as genuine diamonds, but they do not have the tendency and expectation to hold the same or higher value as genuine diamonds in the long term. So if you are thinking about where to put your money for the long term, lab grown diamonds are not a good choice for you.

Moissanite is the second hardest gemstone in the world after diamond. It also has very similar properties – a hardness of 9.25, higher brilliance and even 2.5 times more fire than diamond. Moissanite also has the ability to double refract, which can make its reflections appear iridescent under certain conditions.

Yes. Lab-grown diamonds have much less environmental impact because they do not require the use of heavy equipment during mining, with its associated land degradation, air and water pollution. Lab-grown diamonds also use significantly less energy and water than mined diamonds.

Diamonds can be purchased in a variety of colours including traditional white, yellow, blue, champagne and black. Some companies also offer unique colors such as pink and green.

First and foremost, only purchase lab grown diamonds from a trusted and reliable source, such as a reputable jewelry store. You can also verify its authenticity by using the testers that jewellers provide. If you still want to be sure, visit an independent gemologist for an expert evaluation.

Thanks to the same optical, chemical and physical properties, a lab-grown diamond is just as suitable for an engagement ring as a natural diamond. The advantage is also a lower purchase price.

Over the past year, there has been a noticeable drop in the price of lab grown diamonds. The technology of their production is improving very rapidly and thus their price is falling. This has particularly affected round diamonds, which are the first in terms of demand and best-selling diamonds. In fact, more LG diamond manufacturers have focused on their production. In the case of less traditional cuts, the so-called fancy (oval, drop, emerald, princess, asscher), there has not been such a significant drop in prices yet.

With increasing demand for sustainable, conflict-free gemstones, more and more customers have been turning to lab grown diamonds. If you’re wondering where to purchase such diamonds, take a look at our summary of some well-known retailers.

Laboratory diamonds are produced either by the Chemical Vapour Deposition (CVD method) or by the High-Pressure High Temperature method (HPHT). In the CVD process, carbon atoms are deposited on a substrate of a mixture of hydrocarbon gases, while the HPHT method involves exposing the carbon source to extreme pressure and temperature conditions. Both methods simulate the natural process of diamond formation, allowing the creation of gems identical to natural diamonds.

How long the process takes to create a lab-grown diamond depends on various factors such as the method used (CVD or HPHT), the size and quality of the diamond that’s required and the production capacity of the laboratory. In general, the process can take anywhere from a few days to several weeks. For example, some smaller diamonds can be produced via the CVD process in a few days, while larger or higher quality diamonds may require several weeks.

Some of the names used to refer to lab-grown diamonds include lab diamond, synthetic, cultured, man-made, laboratory created, lab-made and artisan-created. These terms are often used as synonyms for those diamonds that are not of natural origin but are created in a laboratory.
