The following combination of techniques are most commonly used by laboratories:

High-pressure High-temperature (HPHT)

High-Pressure High-Temperature, or HPHT, recreates a diamond's Natural growing environment found deep within the Earth. The growth cell contains all the elements needed to grow a diamond, including a seed, highly refined graphite and a catalyst mixture consisting of metals and powders. This process takes place over several days and allows the carbon atoms to build upon the seed. The cell is removed from the HPHT machine once the growth cycle is complete. The new rough diamond is extracted and cleaned in preparation for final cutting and polishing.

Chemical Vapor Deposition (CVD)

The CVD process uses ultra-pure carbon-rich gasses in a controlled chamber. Carbon based gasses, such as methane, are heated until they break apart allowing the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and build up layers resulting in a rough diamond crystal. This process takes between six to ten weeks and yields gem-grade, Type lla diamonds.


Why Hara Diamond?

Affordable for all Class

Affordable for all Class

Lab-grown diamonds are 30 to 40 % less expensive than mined diamonds. An increased number of the new generation is embracing this ethical choice as they are bigger, better and value for money.

Type IIA

Type IIA

Mined Diamonds are essentially composed of pure carbon. But many diamonds contain traces of impurities such as nitrogen or boron, acquired during the course of formation. Those diamonds that contain little or no impurities are Type IIA diamonds. Less than 2% of mined diamonds are Type IIA and hence are the purest & rarest form of diamonds. All our colorless Lab grown diamonds are Type IIA.

The 4C'S

Just like mined diamonds, every grown diamond is examined by expert gemologists to provide the most rigorous assessment of the four Cs.



Cut measures workmanship. The cut is what reflects luminous light, brightness, dispersion, contrast and scintillation. Precision craftsmanship in our master studio assure Super Ideal cut.



A diamond’s radiance is from its flawlessness. Clarity measures diamond flaws, called inclusions, which might appear as tiny spots, clouds, or cavities.



Colorlessness is a quality. Color is graded by letters ranging from D to Z, starting with D for most rare & colorless diamonds.



Carat is a weight and size measurement. A 1-carat diamond weighs 200 milligrams. But there’s no ideal size for a diamond. It depends on budget and taste. Small diamonds are less expensive than larger diamonds.
