India's New Diamond Labelling Standards: What Lab Grown Diamond Ring Buyers Should Know

Buying a lab grown diamond ring involves more than choosing its design or carat weight. You should also know exactly what type of diamond you are purchasing. To make this clearer, the Bureau of Indian Standards (BIS) introduced IS 19469:2025, a standard that sets guidelines for how natural, laboratory-grown and treated diamonds should be described and advertised in India.

The standard addresses a common problem in the jewellery market: confusing product descriptions that make it difficult for buyers to distinguish between different types of diamonds.

Here's what the new standard means if you are planning to buy a lab grown diamond ring.

What Is BIS Standard IS 19469:2025?

IS 19469:2025 is based on the international standard ISO 18323:2015. It establishes clear terminology for describing diamonds and diamond-like products.

Under this standard, the word "diamond" without any additional description refers to a natural diamond. Laboratory-grown stones must be identified using the terms "laboratory-grown diamond" or "laboratory-created diamond".

The aim is to help customers understand what they are buying without relying on assumptions or unclear marketing language.

3 Important Changes Buyers Should Know

1. Clear Identification of Laboratory-Grown Diamonds

Sellers must clearly distinguish laboratory-grown diamonds from natural diamonds. The standard recognises the terms "laboratory-grown diamond" and "laboratory-created diamond" for these stones.

It also restricts shortened descriptions and abbreviations such as "lab diamond" and "LGD" in commercial descriptions.

2. Misleading Product Descriptions Are Restricted

Terms such as "fake diamond" and "artificial diamond" are not appropriate descriptions for laboratory-grown diamonds. Similarly, sellers should not use language that creates confusion about a stone's origin.

This helps buyers understand the difference between a laboratory-grown diamond and an imitation stone such as cubic zirconia.

3. Diamond Treatments Must Be Disclosed

If a diamond has undergone treatments to change its colour or clarity, this information should be clearly disclosed.

This matters because two diamonds may look similar but have different treatment histories. Knowing these details helps buyers make a better comparison.

What Should You Check Before Buying a Lab Grown Diamond Ring?

Apart from understanding the new labelling standard, check these details before placing an order:

• Diamond origin: Confirm that the product description clearly identifies the stone as laboratory-grown.

• Grading report: Ask for the available diamond grading report and check its details.

• 4Cs: Compare cut, colour, clarity and carat weight rather than choosing a ring based on carat alone.

• Gold purity: Check whether the ring is made in 14KT or 18KT gold and look for applicable BIS hallmark details.

• Invoice: Make sure the invoice clearly mentions the jewellery and diamond specifications.

These checks are particularly useful when purchasing a ring online, where you cannot examine the diamond in person before ordering.

Does IS 19469:2025 Mean Every Lab Grown Diamond Ring Comes with a Certificate?

No. This is an important difference.

IS 19469:2025 deals with diamond terminology and disclosure. It does not automatically certify every laboratory-grown diamond or replace an individual grading report.

A grading report provides information about a particular stone, while the BIS standard explains how different types of diamonds should be described.

Always check what documentation the jewellery brand provides before making a purchase.

Final Thoughts

India's new diamond labelling standard gives buyers clearer information when comparing natural and laboratory-grown diamonds. It also makes product descriptions more important, particularly when shopping online.

Before choosing a lab grown diamond ring, check its origin, grading details, gold purity and invoice specifications. Understanding these details can help you select a ring that matches your expectations and budget.
