Introduction
Priya was excited. She wanted to surprise herself with a beautiful mangalsutra bought online. The photos looked stunning, the price was low, and the seller promised “pure diamonds.” A week later, the product arrived—and it was nothing like the pictures. No certificate, poor shine, and the seller stopped replying. Priya lost her money and her trust.
Stories like this are common today.
At the same time, lab grown diamond mangalsutra designs are becoming very popular. In fact, lab grown diamonds made up around 25% of India’s jewellery market in 2025, thanks to better prices and ethical benefits.
This blog is written to help you avoid mistakes, spot genuine quality, and buy with confidence. Follow these checks before you buy, and you’ll get real value—not regret.
Understand Lab Grown Diamonds Basics
What Makes Lab Grown Diamonds Special?
Lab grown diamonds are real diamonds. They are created in advanced laboratories using technology that copies how diamonds grow naturally under the earth.
There are two main methods:
CVD (Chemical Vapor Deposition)
HPHT (High Pressure High Temperature)
Both produce diamonds with the same sparkle, hardness, and chemical structure as mined diamonds.
According to a GIA 2025 report, lab grown diamonds cost 30–40% less than mined diamonds of the same quality.
Action tip:
Always confirm whether the diamond is CVD or HPHT. This information should be clearly mentioned on the product page or certificate.
Myths to Bust
Many buyers still hesitate because of myths. Let’s clear them.
Myth: Lab grown diamonds do not sparkle like natural diamonds
Fact: Under professional testing, lab and mined diamonds look identical.
As jeweller Ravi Mehta says:
“Lab diamonds match mined ones in beauty and strength. Even experts need tools to tell them apart.”
Key takeaways:
Always check for IGI or GIA certification
Never buy uncertified diamonds
Sparkle depends on cut, not origin
Real-World Example
A shopper in Mumbai compared two mangalsutras—one with a mined diamond and one with a certified lab grown diamond. Same size, same design.
By choosing lab grown, she saved ₹50,000.
