What Are Lab Grown Diamonds?
CVD Lab Grown Diamonds are produced by placing a diamond seed crystal inside a chamber filled with carbon-rich gas. The gas is activated into plasma, allowing carbon atoms to deposit and crystallise layer by layer onto the seed. This method consistently yields high-purity Type IIa CVD diamonds with exceptional optical clarity and strong colour grades.
HPHT Lab Grown Diamonds replicate the extreme heat and pressure conditions found deep within the earth. A carbon source is subjected to temperatures above 1,400 degrees Celsius and pressures exceeding 50,000 atmospheres, producing diamonds with characteristics identical to mined stones.
Both CVD and HPHT lab grown diamonds are physically, chemically, and optically identical to natural diamonds. Standard gemological tests cannot distinguish them from mined stones without specialised equipment. At Mann Gems, we stock both varieties and clearly disclose the growth method on all certification reports, ensuring complete transparency for every buyer.
Natural Diamonds vs Lab Grown Diamonds
From a gemological standpoint, lab grown diamonds and mined diamonds are evaluated using the same internationally recognised 4Cs framework: Carat, Cut, Colour, and Clarity. At Mann Gems, every diamond is graded to the same standards applied by IGI and GIA.
Colour: Lab grown diamonds are frequently available in higher colour grades such as D, E, and F due to the controlled growth environment, making them a preferred choice for buyers seeking white lab grown diamonds with outstanding brightness and visual appeal.
Clarity: The CVD process in particular yields diamonds with fewer inclusions, resulting in VVS and VS clarity grades that are more consistently accessible in the lab grown diamond range compared to equivalent mined stones.
Price: Lab grown diamonds in India are typically 50 to 70 percent more affordable than natural diamonds of equivalent carat weight and quality. This pricing advantage allows buyers to select larger carat sizes or superior colour and clarity grades within the same budget, which is a primary driver of demand for loose lab grown diamonds for sale across India and international markets.
Cut
The cut of a natural diamond decides how well it reflects light, directly affecting its brilliance and sparkle.
COLOR
Lab grown diamonds are commonly available in higher colour grades, offering a bright and clean appearance.
CLARITY
Controlled growth often results in fewer inclusions, leading to high clarity grades.
CARAT
Larger carat sizes are more accessible, making lab grown diamonds ideal for bold designs.
Lab Grown Diamond Cost in India and Availability for Sale
The lab grown diamond price per carat in India varies based on growth technology, colour grade, clarity, cut, and certification. As a reference, a 1-carat DEF colour, VVS clarity CVD lab grown diamond with an IGI grading report is available at a significantly lower price than a comparable mined diamond, offering exceptional brilliance and verified quality within a practical budget.

FAQs – Lab Grown Diamonds
CVD (Chemical Vapour Deposition) diamonds are grown by depositing carbon atoms from a gas onto a seed crystal in a controlled chamber. HPHT (High Pressure High Temperature) diamonds replicate the natural geological process using extreme heat and pressure. Both produce genuine diamonds with the same physical and optical properties as mined stones. CVD diamonds often achieve very high colour purity, while HPHT is frequently used for certain fancy colour production. Mann Gems stocks both varieties with full growth method disclosure on every certification report.
IGI certified lab grown diamonds carry comprehensive grading reports that confirm carat weight, cut, colour, clarity, and growth method.
