Lab Grown Diamond Rings for Women

Lab Grown Diamond Rings Online

Lab grown diamond rings in this collection are set with real diamonds. Not simulants, not moissanite. Real diamonds, grown in a laboratory using CVD (Chemical Vapour Deposition) or HPHT (High Pressure High Temperature) technology.

The result is a stone that is chemically, physically, and optically identical to a mined diamond. Same carbon structure. Same hardness, 10 on the Mohs scale. Same refractive index, the same fire, the same brilliance.

Every diamond in this collection is certified by IGI. The certificate documents the 4Cs: cut, colour, clarity, and carat. It explicitly states "Laboratory Grown." This is what separates a certified lab grown ring from an uncertified simulant.

Goenka Jewellers has manufactured lab grown diamond jewellery in Kolkata since 2006. The collection spans 1 to 18 carats, set in 14K and 18K BIS hallmarked gold.

Ring Styles in This Collection

Solitaire Rings

One diamond, centre-set. Available in round brilliant, oval, pear, princess, and cushion cuts. Round brilliant reflects the most light. Oval creates the appearance of a larger stone for the same carat weight, a practical choice if size on finger matters. The most-purchased style for engagements in this collection.

How to Choose a Lab Grown Diamond Ring

Start with cut, not carat. Cut grade determines how much light returns through the top of the stone. An Excellent-cut 0.7ct diamond will visually outperform a Fair-cut 1ct stone. This is the most common mistake buyers make.

On colour: D to F grades are colourless. G to I are near-colourless. The difference is not visible to most people without a comparison stone beside it. G to I is a reasonable budget choice.

On clarity: VVS1 and VVS2 are the clarity grades we recommend. Their inclusions are so minute that they are extremely difficult to find even under 10x magnification, so the diamond looks flawless at every carat weight.

On metal: 18K gold is 75% pure and looks richer, especially in yellow gold. 14K is 58.5% pure and harder, better for rings worn every day. Both options in this collection are BIS hallmarked.

One thing worth knowing before buying: lab grown diamonds are real diamonds, with the same brilliance, hardness and IGI certification as mined diamonds, at almost 90% less. That saving buys a bigger, better-graded stone, and Goenka's exchange and cash buyback at 100% of the gold value and 80% of the diamond value at market rate (T&C apply) protects your purchase. For a certified, brilliant diamond ring, lab grown is simply the smarter choice.

For ring sizing, Goenka offers complimentary resizing within 30 days of delivery if ordering online.

Lab Grown vs Natural Diamond Rings

Lab grown diamonds and natural diamonds differ only in origin and price:

• Carbon structure: Identical in both. Same hardness of 10 on the Mohs scale, same refractive index, same fire and brilliance.

• Certification: Both carry IGI grading certificates with full 4Cs documentation.

• Price: Lab grown costs almost 90% less than a natural diamond of the same cut, colour, and clarity grade.

• Origin: Lab grown from a CVD or HPHT laboratory. Natural from earth-mined sources.

• Value: Lab grown puts a bigger, finer, certified diamond within your budget, and every Goenka piece comes with exchange and cash buyback at 100% of the gold value and 80% of the diamond value at market rate (T&C apply).

The price gap is the main reason most buyers choose lab grown. A lab grown diamond costs almost 90% less than a mined diamond of the same grade.
