Gemstone certification is becoming vital for India’s fast-growing jewellery market. A certified gemstone comes with a report from an independent lab. The report verifies the stone’s type, quality, weight, colour, and whether it is natural or lab-grown. It also confirms the gemstone’s origin and any treatments done to enhance its appearance.
“Certification is like a guarantee for buyers,” said Ramit Kapur of Gemological Science International (GSI).
GSI runs labs in Jaipur, Mumbai, and other cities, checking thousands of gemstones every day.
India’s jewellery market is booming. The government wants the industry to touch $200 billion by 2030. Experts say trust and transparency will be key to meet this goal.

Younger buyers, especially millennials and Gen Z, are driving the demand for certified coloured gemstones. Many see them not just as jewellery but as a form of investment. Stones like emeralds can rise sharply in value if they come with trusted proof of origin.
Ramit Kapur noted that many buyers still do not know the difference between natural and lab-grown diamonds. Both the diamonds have different origin and different characteristics, hence they are not same.
So what should buyers look for? Kapur said to always check if a gemstone comes with a certificate from an accredited lab — look for labs approved by bodies like the Bureau of Indian Standards or the Responsible Jewellery Council.
Physical and digital certificates are both valid. Many labs now offer digital reports that can be verified online. This makes it harder for fake stones or fake reports to slip through.
As exports grow, so does the need for strict grading and ethical sourcing. Certification helps track where stones come from and ensures they meet global standards.
“Certification builds confidence,” Kapur said. “It protects buyers and keeps the industry honest.”
