Diamonds of laboratory origin are genuine diamonds

Lab grown diamonds have identical physical and optical properties to natural diamonds. They are equally beautiful, durable and excel in high clarity. And each one is an original.

How is the production?

Why choose
lab grown diamonds?

Gentle production

They are a responsible choice – thanks to the production in the lab, no diamonds are mined.

Same quality

They have exactly the same
chemical and physical composition.

Better price

In comparable size and quality are
more cost-effective than natural diamonds.

Benefits of
laboratory diamonds

Lab grown diamond is a real gem. It is formed under the same temperature and pressure conditions as natural diamond and thus achieves an identical composition. Thanks to a very strictly controlled and monitored production process, it often achieves much better quality.

What are the other benefits?

Perfect purity and internal structure at a good price

Much shorter laboratory synthesis process compared to natural formation

Less defects = much more diamonds for sale

Wide colour availability – unique and desirable colours rarely found in nature

Ecology and provenance – environmentally friendly and traceable source of diamond origin

Sustainable manufacturing process using gas atom layering (CVD method)

How are lab grown diamonds produced?

Diamonds created in the lab are made using a process called CVD (chemical vapour deposition). In this process, a small germ crystal is placed in a sealed chamber and a combination of carbon- and hydrogen-rich gases is then heated at high temperatures and broken down into its individual atomic components. Under intense heat and pressure, the carbon atoms then attach to the surface of the aforementioned germ crystal, forming a layer of pure crystalline diamond. This process is repeated several times, layer by layer, until a full diamond is formed.

Another less used and less costly method is High Pressure-High Temperature (HPHT).

Most frequently asked questions

Still haven’t found the answer to your question? Check out our list of frequently asked questions to help you buy a diamond.

What is the difference between lab-grown and natural 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.

Are lab-grown diamonds cheaper?

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.

Can we consider lab grown diamonds a good investment?

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.

What is the difference between lab-grown diamond and moissanite?

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.

Do lab grown diamonds have less impact on the environment?

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.

In what colour shade can I buy 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.

How do I know if a lab grown diamond is real?

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.

Is a diamond created in a laboratory suitable for an engagement ring?

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.

Why has the price of lab diamonds dropped?

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.
