Lab Grown Diamond Necklace for Women

Lab Grown Diamond Necklaces Online

Lab grown diamond necklaces in this collection are set with real diamonds. Not cubic zirconia, not moissanite. Real diamonds, grown in a laboratory using CVD or HPHT technology, certified by IGI.

Every certificate documents the diamond's 4Cs: cut, colour, clarity, and carat. It explicitly states "Laboratory Grown." This is the only difference from a mined diamond. The carbon structure, hardness, refractive index, and brilliance are identical.

Whether you are looking for a lab grown diamond necklace for daily wear, a gift, or a special occasion, this collection covers pendants, sets, tennis necklaces, and layering styles in 14K and 18K BIS hallmarked gold.

Goenka Jewellers has manufactured lab grown diamond jewelry in Kolkata since 2006. Pieces are sold directly, without retail markup.

How to Choose a Lab Grown Diamond Necklace

For pendants and solitaires, start with diamond shape. Round brilliant reflects the most light and is the most popular. Oval and pear create an elongating effect on the neckline.

On chain length: 16 inches sits at the collarbone. 18 inches falls just below. 20 to 24 inches is a longer, layering length. For sets, chain length is usually fixed to the pendant design.

On carat for necklaces: 0.3ct to 0.7ct pendants are the most practical daily wear range. For statement pieces and sets, 1ct total weight and above gives visible presence.

On metal: White gold shows diamond brilliance most clearly. Yellow gold is warmer and complements most skin tones. Rose gold is a contemporary choice. 18K is richer in colour. 14K is harder and more durable for daily wear.

Lab Grown vs Natural Diamond Necklaces

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).

Lab grown diamonds cost almost 90% less than natural diamonds of the same grade. This means a 1ct lab grown diamond solitaire necklace in 18K gold is accessible at a price that a natural diamond equivalent is not.
