Lab Grown Diamond Mangalsutra, IGI Certified

This collection covers lab grown diamond mangalsutra in traditional and contemporary designs. All pendants set with IGI or GIA certified lab grown diamonds in 14K and 18K gold. Black bead chains in silk thread, gold chain, and combination options.

Lab grown diamond mangalsutra pendants are real diamond jewellery. The diamonds are physically identical to mined diamonds. The difference is origin and price. A certified 0.5ct lab grown diamond mangalsutra pendant costs Rs.35,000 to Rs.60,000 at Goenka. A natural diamond equivalent starts at Rs.90,000.

Goenka Jewellers has manufactured diamond mangalsutra designs in Kolkata since 2006. Traditional designs with contemporary finishing, available in yellow and white gold, with customisation on pendant shape and chain length.

Mangalsutra Styles in This Collection

Traditional Pendants

Classic double-pendant designs in 14K yellow gold with black bead accents and certified lab grown diamonds. The traditional shape is maintained, with IGI or GIA certified stones replacing natural diamonds.

Contemporary Single Pendants

Single, modern pendant designs suitable for daily wear. Less weight than traditional double-pendant styles. Available with silk thread, gold chain, and combination chains.

Solitaire Mangalsutra

A single large diamond as the mangalsutra pendant. Available from 0.3ct to 1.5ct. A popular choice for women who prefer minimal jewellery. Also available as solitaire pendants in non-mangalsutra settings.

Floral and Cluster Designs

Multi-stone pendants in floral arrangements. Gives significant visual presence at lower total carat weight than a single solitaire.

Designer and Artisan Mangalsutra

Custom and artisan designs with IGI or GIA certified lab grown diamonds. Lead time 2 to 3 weeks for custom pieces.

Gold Chain Mangalsutra

Pendants on 18K gold chains rather than silk thread. More formal and suitable for occasions. Also available in combination (gold chain with black bead sections).

Chain Options

Silk thread with black beads. The most traditional option. Lightweight, daily wear. Thread can be replaced at any Goenka boutique.

Gold chain with black bead sections. A contemporary interpretation of the traditional design. More durable than pure silk thread.

Full gold chain. 18K gold chain with no black beads. More formal. Commonly chosen for occasions where a mangalsutra needs to look like fine jewellery rather than traditional wear.

Lab Grown vs Natural Diamond Mangalsutra

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 or GIA grading certificates with full 4Cs documentation.

•     Price: Lab grown costs 60 to 75% 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.

•     Secondary market: Lab grown has a lower secondary resale market at this time. Natural diamonds have an established resale market. Worth knowing before purchase.

The savings are significant for mangalsutra where the pendant diamond is worn every day for years. A 0.7ct lab grown diamond mangalsutra in 18K yellow gold costs Rs.55,000 to Rs.80,000 at Goenka. A natural diamond of the same grade runs Rs.1,40,000 or more.

Price Ranges

•     Under Rs.25,000 - 0.1ct to 0.3ct, 14K gold. Best for: Daily wear, minimal designs, gifting.

•     Rs.25,000 to Rs.60,000 - 0.3ct to 0.7ct. Best for: Traditional and contemporary designs.
