What Are Lab Grown Diamonds?

Lab grown diamonds are real diamonds, not simulants, not fakes. They are created in controlled laboratory environments using two scientific processes: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods replicate the conditions under which natural diamonds form deep within the Earth.

The result? A diamond that is chemically, physically, and optically identical to a mined diamond. The only difference is origin, and price.

What Affects the Price of a Lab Grown Diamond?

The 4Cs of Diamond Pricing

Just like natural diamonds, lab grown diamonds are graded on the 4Cs, and each one directly influences the price.

1. Carat (Weight) Carat is the most straightforward price driver. A 1-carat lab grown diamond costs significantly more than a 0.50-carat stone of the same quality. Prices increase non-linearly, so a 2-carat diamond is not simply twice the price of a 1-carat.

2. Cut Cut determines how well a diamond reflects light. An Excellent or Ideal cut brings out maximum brilliance and commands a premium over Good or Fair cuts. Never compromise on cut, as it is what makes a diamond truly sparkle.

3. Colour Diamonds are graded from D (completely colourless) to Z (visibly yellow). For most buyers, a stone in the G–H range offers an excellent balance of colour quality and price. D–F stones are premium and priced accordingly.

4. Clarity Clarity measures internal flaws (inclusions) and surface blemishes. Grades range from FL (Flawless) to I3. For everyday jewellery like engagement rings and earrings, VS1–VS2 or SI1 stones offer great value with no visible inclusions to the naked eye.

HPHT vs CVD: Does the Process Affect Price?

Both HPHT and CVD diamonds are equally real. However, CVD diamonds tend to be slightly more affordable at higher carat weights, which is why most lab grown diamonds above 1 carat sold in Chennai are CVD. The process does not affect quality, only production cost.

Certification

A certified diamond from IGI (International Gemological Institute) or GIA always carries a small premium over an uncertified stone, and rightly so. Certification guarantees the 4Cs are accurately graded, protects your investment, and is essential when buying online or reselling later.

Lab Grown vs Natural Diamond Price in Chennai

Feature	Lab Grown Diamond	Natural Diamond
1 Carat Price	₹35,000 – ₹70,000	₹2,50,000 – ₹5,00,000+
Certification	IGI / GIA	IGI / GIA
Quality	Identical	Identical
Resale Value	Moderate	Moderate to High
Ethical Sourcing	Guaranteed	Varies
Availability	High	Limited

The price advantage is clear. For the same budget, you can get a significantly larger or better-quality lab grown diamond. A buyer looking at a 0.50-carat natural diamond can often afford a 1.50-carat lab grown diamond of equal or better grade.

Tips to Get the Best Price on Lab Grown Diamonds in Chennai

1. Don't chase the highest carat at the cost of cut. A well-cut 0.80-carat diamond will look more brilliant than a poorly cut 1-carat stone. Cut quality should never be compromised.

2. Choose G–H colour and VS2–SI1 clarity for maximum value. These grades look beautiful in real-world settings and save significant money compared to D–FL stones.

3. Always ask for the certificate. An IGI or GIA certificate is your guarantee of quality. Never purchase a diamond, lab grown or natural, without one.

4. Buy slightly below whole-carat milestones. Diamonds priced at 0.90 ct look almost identical to a 1.00 ct stone but cost noticeably less. The same applies to 1.90 ct vs 2.00 ct.

5. Visit the showroom in person. Seeing a diamond in person under different lighting conditions gives you a far better sense of brilliance and quality than photos alone.
