What are Lab Grown Diamonds

Lab grown diamonds or man made diamonds are diamonds that are grown in labs using advanced reactors that mimic the conditions under which diamonds naturally develop under the earth. They are physically, chemically and optically the same as natural diamonds. Think of lab grown diamonds as test tube babies – the process of formation may be different but the end product is the same! Lab diamonds are true to the environment and the future – they are not mined and hence prevent damage to the planet. Ethical and sustainable is the way to go!

How Are Lab Diamonds Made

Lab Grown Diamonds are made in labs under conditions that are similar to the conditions under which diamonds develop naturally under the earth’s crust. They can be produced through High Pressure High Temperature Process (HPHT) or Chemical Vapor Deposition Process (CVD).

In the HPHT process, a diamond seed is subjected to intense pressure and temperature, emulating the Earth's mantle conditions, prompting the growth of a diamond.

CVD involves ionizing a carbon-rich gas mixture in a vacuum chamber, leading to the deposition and crystallization of carbon atoms on a substrate, ultimately forming a diamond layer. These techniques yield diamonds with comparable properties to natural ones.


Lab Grown Diamonds are diamonds that are created in a laboratory setting rather than being mined from the Earth’s crust. These laboratories mimic the conditions under which diamonds naturally develop under the earth over millions of years. They are physically, chemically and optically the same as natural diamonds. Even jewellers and gemologists cannot tell the difference between lab grown and natural diamonds.

Lab Grown Diamonds are real diamonds. Despite being grown in reactors in labs, these diamonds possess the same physical and optical characteristics as natural diamonds. 

Any diamond is a diamond not because it is mined from the earth but because of its chemical composition. Both Lab Grown Diamonds and natural diamonds possess the same crystalline structure of carbon atoms. Hence Lab Grown Diamonds are real diamonds.

There is no way of differentiating between a lab diamond and a natural diamond by looking at them. Even a trained jeweller or expert cannot tell the difference between natural and Lab Grown Diamonds with their naked eyes or with normal microscopes. Only advanced equipment in gemological labs can identify Lab Grown Diamonds.

Lab Grown Diamonds are worth buying because they are diamonds and they last forever. Just as jewellers offer buyback on natural diamonds, Jewelbox offers buyback on Lab Grown Diamonds too. Jewelbox offers 80% buyback on Lab Grown Diamonds.

Yes. Lab Grown Diamonds tend to retail at a 60-90% discount on equivalent quality of natural diamonds. Lab Grown Diamonds are priced based on cut, colour, clarity and carat – just like natural diamonds.

Lab created diamonds are graded the same way as mined diamonds. They are certified by all the leading gemological labs such as IGI, GIA, SGL, EGL. All the Lab Grown Diamonds used by Jewelbox are graded and certified by renowned third party organisations.

Lab Grown Diamonds are not synthetic diamonds or Cubic Zirconia or Moissanite. CZ or Moissanite are diamond simulants and not diamonds. Lab Grown Diamonds on the other hand are real diamonds.

Diamonds are the hardest material on earth. They rank at 10 on Mohs Scale of hardness. Lab Grown Diamonds as well as natural diamonds have this same rank of 10, which means they’re extremely durable. Lab Grown Diamonds match their mined counterparts in hardness, strength and durability! Take comfort knowing Lab Grown Diamonds are strong enough to hand down to the next generation.

No. Lab Grown Diamonds do not fade, discolour or cloud over time. Their beauty is timeless.

No. A lot of people think that machines can be programmed to create a specific diamond grade and carat size but that’s really not possible. Machines simply put the right conditions together but then nature takes it from there. Just like with mined diamonds, there will be variances in colour, clarity and carat size in every piece.

Yes, Lab Grown Diamonds are also characterised based on the 4Cs – Cut, Colour, Clarity and Carat – just like natural diamonds.
