What are Lab Grown Diamonds?

Lab-Grown Diamonds are chemically, optically and physically similar to earth-mined diamonds but are created in a controlled environment making them more ethical and affordable.

These diamonds are “grown” inside a lab using cutting-edge technology that replicates the earth’s natural processes to form diamonds. Lab-grown diamonds are indistinguishable by the naked eye from mined diamonds and are 100% conflict free and sustainable.

How are lab grown diamonds made?

While mined diamonds are formed deep in the Earth’s crust over millions of years, lab grown diamonds are grown using cutting edge technology within weeks. Lab grown diamonds can be made using two processes:

The HPHT method:

A “diamond seed” is placed along with carbon in containment chambers. High pressure and high temperatures are applied to mimic the conditions under which mined diamonds are formed. The carbon melts and is carefully cooled to form diamond crystals. The HPHT process can take from hours to weeks, depending on the desired size and quality of the stones.

The CVD process:

Uses low pressures and high temperatures in a vacuum chamber to produce diamonds. Carbon-rich gases such as Methane are introduced into the chamber that crystallize on a diamond seed. CVD can take from days to weeks, depending on the desired size and quality of the stones. However, dozens of stones can be grown at the same time.

Both HPHT and CVD produce diamonds with the same optical, physical, and chemical properties as mined diamonds.

How are Lab Grown Diamonds Evaluated?

The 4C’s, colour, cut, carat weight and clarity, together, are used to evaluate the quality of diamonds, and subsequently the value and rarity of the diamond. These characteristics can vary from diamond to diamond and each of the 4C’s contribute equally to the beauty and shine you see on the final finished diamond.


Diamonds come in a variety of colours ranging from colourless to light yellow to brown. GIA’s D-to-Z scale is the industry standard for colour grading diamonds. Lighter the colour, the more rare the diamond. Many colour distinctions are unnoticeable to the human eye, but these subtle differences can dramatically affect diamond value.


Often confused with shape, the cut of a diamond refers to how well a diamond's facets interact with light. The quality of the cut is crucial to determining its value. GIA evaluates the cut of a diamond on seven components. The first three; brightness (white light reflections), fire (flashes of colour) and scintillation (areas of light and dark), are concerned with the outer appearance. The other four; weight ratio, durability, polish and symmetry, focus on the diamonds internal design and craftsmanship.


A diamond’s clarity refers to the presence of impurities on and within the stone. These imperfections, called flaws or inclusions, may be present even when grown in a lab. Evaluating the clarity involves determining the degree to which the size, number, and position of these inclusions affect the overall appearance of the diamond. The fewer the flaws, the higher the value and price of the diamond. The GIA Clarity Scale is 6 main categories which can be further divided into 11 subcategories of grades. Most of these flaws are not visible to the naked eye and require a skilled professional to use about 10x magnification.

Carat Weight

The diamond carat weight is a measurement of how much the diamond weighs, and a ‘carat’ is defined as 200 milligrams. The metric ‘carat’ can be divided into 100 points which allows for very accurate measurements. While each of the 4C’s should be taken into consideration for evaluating the value of a diamond, the price of a diamond increases as the carat weight increases.

Lab Grown Diamonds (also known as man made diamonds) are redefining the jewellery industry by being the new age, affordable and ethical alternative to mined diamonds. Created from a deep desire to bring aspirational luxury to the world, these are grown by replicating the earth’s organic processes by experienced scientists. Made of the same DNA and carbon as mined diamonds, Lab Grown Diamonds are physically, chemically, and optically identical to mined diamonds. Learn more about Lab Grown Diamonds here.

Lab Grown Diamonds are authentic in every sense of the word. All their physical, chemical, optical and atomic properties are identical to those of mined diamonds. These diamonds are also certified by international gemological institutes, the same institutions that certify mined diamonds. Lab grown diamonds can also be insured. The only difference is that they are made above ground instead of below ground. On the other hand, diamond simulants such as moissanites and cubic zirconia are not actual diamonds, but merely resemble them because they do not have the same chemical & physical properties of a mined diamond.

A diamond ‘seed’ is set in carbon-rich conditions inside a sophisticated growth chamber. Using exclusive growth techniques, the seed develops into a rough diamond. The rough diamond is then planned, laser cut, polished & finished just like a mined diamond is. This turns it into a lovely, sparkling precious stone. Depending on the size, it can take anywhere from 3-12 weeks. There are two processes that are used to grow lab grown diamonds: High Pressure, High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

Lab created diamonds offer excellent value, and are more affordable than mined diamonds of comparable size and quality.

Yes, Lab Grown diamonds come in the same colours and purity as Earth Grown. We sell stones from Internally Flawless to SI2 and from D-I in colour.

Yes, Lab Grown diamonds have essentially the same chemical composition and crystal structure as mined diamonds and will test as real diamonds. 

Yes, we sell a variety of shapes, mainly Round, Oval, Emerald, and Cushion Cut. All these shapes can be made to different sizes. 

Our diamonds come directly from the manufacturing source, cutting out the middleman and therefore offering diamonds directly to the public at wholesale prices.

Every lab grown diamond is unique, and it is almost impossible to replicate a lab grown diamond. Human interaction in creating Lab Grown Diamonds is limited to the introduction of the diamond seed in the growth chamber and ensuring a dust free environment. After which, nature takes over. There are many factors that can affect the outcome of the diamond crystal, making it very difficult to control the exact growth process. The 4C’s determine the final value of each diamond grown. 

All diamonds are evaluated on 4 factors: cut, colour, clarity, and carat. Together, these are popularly known as the 4 Cs.

Cut: The way a diamond has been cut and polished; its symmetry and proportions are completely dependent on human intervention. The cut is a significant factor in determining the gem’s brilliance and value. It’s arguably the most important criteria to consider while selecting.

Colour: Diamonds come in a range of colours: from colourless to yellow; brown to grey. A diamond is compared to a globally accepted master set to determine its colour value. The range spans from the most sought after colourless, D; to the least desirable colour, Z. Deeply saturated hues occur in coloured diamonds, the most intense of which are graded as “fancy” and sell for higher prices. So, a colourless diamond will be most expensive followed by a fancy colour followed by a light colour.

Colourless: Colourless diamonds (shades D to F) are the slowest and most difficult diamonds to grow. Yet, these rare phenomena are the most sought after. They are followed by the near colourless (shade G to I), which are relatively faster to grow than the colourless ones. Some popular offered colours in Lab Grown Diamonds are blue, pink & yellow.

Clarity: All diamonds have a few imperfections, both within (inclusions) and on the surface (blemishes). Greater clarity is desirable and leads to higher value. To arrive at a clarity grade, the size, colour, number, relief, nature and position of a diamond are analysed by qualified gemmologists under a loupe and microscope. The standard grades of clarity are given below:

FL: Flawless This grade is given to diamonds that are free from inclusions and blemishes under 10x magnification. Understandably, these are the rarest and costliest.

IF: Internally Flawless This grade is for diamonds with no inclusions and small blemishes visible under 10x magnification.

VVS-1: Very, Very Slightly Included 1 This grade covers diamonds with minute inclusions that are very difficult to locate under 10x magnification.

VS1-2: Very Slightly Included 2 This grade is given to diamonds with minor inclusions that are fairly difficult to locate when examined under 10x magnification.

SI1-2: Slightly Included This grade is for diamonds with noticeable inclusions, which are easily visible under 10x magnification.

Carat: The metric carat is used to measure the weight of gemstones. Each metric carat is equal to 0.20 grams, with 100 points or 200 milligrams per carat. Greater weight of a stone usually means higher value in the case of diamonds.
