 IIGJ Lab is committed to serve the Gem & Jewellery Industry by providing independent quality assessment of Gemstones & Jewellery. IIGJ’s Ruby Identification service is well known and is availed by gemstone manufacturers, traders, and retailers.

Effective 6th November 2025, IIGJ Lab (A Project by GJEPC India) sponsored by Ministry of Commerce and Industry, Govt. of India has updated description for ruby treatments to harmonise with major gemmological laboratories, maintaining highest levels of scientific analysis and transparency.

IIGJ Lab is a project of the Gem & Jewellery Export Promotion Council – sponsored by The Ministry of Commerce & Industry, Government of India. Mission of the Lab is to help trade and consumers to make informed choice.

Rubies are commonly heated using substances like fluxes (e.g. borax), which often is mixed with silica-based materials or high-density glass containing elements like lead (Pb), bismuth (Bi), barium (Ba), yttrium (Y), zirconium (Zr), etc. Under the current policy all these components are mentioned separately, which is now updated to reflect more unified and simplified descriptions on the ruby reports issued by the IIGJ Lab.

Harit Zaveri Jewellers Celebrates A Bride’s Royal Spirit In An Indian Wedding With Its New Polki Collection

A Celebration Of Regal Femininity, Heirloom Craftsmanship, and The Refreshing Depth Of Emeralds.

Published

on

June 2026 A bride’s jewellery is never merely ornamental, it carries sentiment, memory, and the quiet power of tradition. With its newest Polki Collection, Harit Zaveri Jewellers introduces a refined take on royal Indian bridal jewellery, thoughtfully designed for the modern bride who embraces heritage while expressing her individuality with confidence and grace.

Crafted between 18kt to 14kt gold and enriched by Emeralds, Harit Zaveri Jewellers Polki collection celebrates a bride in her most transformative moment – poised between reflection and becoming. Every jewellery piece in the collection is designed to accompany her through this pause.

At the heart of the collection lies the richness of polki craftsmanship – raw, uncut diamonds admired for their old-world charm and regal appeal, long associated with royal Indian heirlooms. Paired with vivid emeralds, known to symbolise renewal, harmony, love, and abundance, the collection brings together heritage and elegance. The richness of green emeralds adds depth and freshness, creating jewels that feel both classic and strikingly modern.

The collection features an expansive range of statement and versatile pieces including necklaces, kadas, rings, earrings, and bridal sets, thoughtfully embellished with emeralds, pearls, and polki detailing.

This collection from Harit Zaveri Jewellers compliments classic reds and heritage weaves to contemporary ivories, pastels, and couture silhouettes. Whether layered with a traditional lehenga, paired with a modern sari drape, or styled for intimate pre-wedding celebrations, these pieces seamlessly adapt while elevating every bridal look with a quiet majesty.

These pieces are envisioned as modern heirlooms, where meticulous craftsmanship, precious materials, and timeless artistry come together to create pieces worthy of being passed down through generations.

Harit Zaveri, Joint Managing Director at Harit Zaveri Jewellers said:

“At Harit Zaveri Jewellers, we have always believed bridal jewellery should feel personal, something that reflects a bride’s story and individuality. Many of our clients naturally gravitate towards one-of-a-kind pieces that resonate with their personality and become part of their memories for years to come. With this Polki collection, we wanted to celebrate craftsmanship with the richness of emeralds, a stone that beautifully complements a variety of bridal colours and effortlessly completes a look. Above all, quality remains at the heart of everything we create because we believe jewellery should feel as enduring as the memories and moments attached to it.”
