Lab Grown Diamond Bangles, IGI Certified

Diamond bangles are one of the most traditional fine jewellery categories in India. This collection covers kadas, cuff bangles, half-set diamond bangles, and full-set designs in 14K and 18K gold with IGI or GIA certified lab grown diamonds.

Lab grown diamond jewelry in the bangle category covers pieces for daily wear through to wedding sets. All diamonds in this collection are real diamonds, identical in composition to mined stones. Also see diamond bracelets for chain-based wrist jewellery.

Goenka Jewellers has made diamond bangles in Kolkata since 2006. Custom sizes available. Bangle sizing in Indian standard sizes 2.2 through 2.12.

Bangle Styles in This Collection

Diamond Kadas

Wide gold bangles with a rigid opening. Worn on the wrist and taken on and off through the hand. Available in 14K and 18K gold with full or partial diamond settings. A traditional design with significant gold weight.

Diamond Cuff Bangles

Open-ended cuff design that can be adjusted to fit different wrist sizes. More flexible than a closed bangle. Diamond settings along the outer face. Easier to put on and take off than traditional kadas.

Half-Set Diamond Bangles

Diamond set across the outer half of the bangle only. The inner surface is plain gold and more comfortable against the skin. Can be stacked. Total diamond weight typically 0.3ct to 1.5ct.

Full-Set Diamond Bangles

Diamonds set all the way around the bangle. Maximum visual impact. Higher total carat weight. Typically worn for weddings, receptions, and significant occasions.

Stackable Diamond Bangles

Thin bangles with small diamond accents designed to be worn in multiples. Each bangle has 0.1ct to 0.3ct of total diamond weight. A set of 5 to 7 stacked together creates a substantial bridal look.

Openable Hinged Bangles

Bangles with a hinged opening and box clasp. Useful for buyers with wider hands who find standard kadas difficult to put on. Available in half and full diamond settings.

Lab Grown vs Natural Diamond Bangles

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.

A half-set diamond bangle in 18K gold with 0.7ct total weight costs Rs.65,000 to Rs.95,000 at Goenka in lab grown. A natural diamond bangle of the same grade and weight starts at Rs.1,60,000 or more.
