BIS norms to boost transparency in lab-grown diamond market
The Bureau of Indian Standards (BIS) has introduced new rules to make it clear when diamonds are made in a lab instead of being natural.
This is important because lab-grown diamonds are much cheaper and some people might try to sell them as real diamonds.
A company called Greenlab Diamonds is doing well in places like Ayodhya, selling lab-grown diamonds without needing to explain much to customers.
The new rules will help people trust that they are buying what they are told, and it will stop dishonest sellers.
Lab-grown diamonds are 90% cheaper than real ones, which makes them popular, especially with younger buyers.
Even though exports of both types of diamonds have gone down a bit, the new rules are expected to make the market more honest and transparent.
BIS introduces mandatory disclosure norms for lab-grown diamonds to enhance transparency and curb mis-selling.
Greenlab Diamonds reports strong sales in Ayodhya, with monthly revenue of ₹30–40 lakh from lab-grown diamonds.
Lab-grown diamonds are 90% cheaper than natural diamonds, appealing to younger and first-time buyers.
Exports of both natural and lab-grown diamonds declined in 2025 due to global slowdown.
Industry experts believe BIS norms will increase consumer trust and weed out unscrupulous sellers.
