Mumbai is the heart of India's gem and jewellery trade.

When you buy a ruby, emerald, or sapphire, you're not just purchasing a beautiful stone — you're investing in something whose value can vary dramatically based on where it came from .

That's exactly what Gemstone Origin Testing is all about. At Mahavir Gemological Laboratory , we've been helping gem traders, jewellers, and buyers in Mumbai understand the true identity and value of their gemstones since 1989.

  Walk into any jewellery showroom in India today and you will hear a term that barely existed a few years ago: lab-grown diamond . Some sellers present them as a revolution. Others dismiss them. And most buyers are left wondering — what exactly is a lab-grown diamond, how is it different from a natural one, and which one should I actually buy? This guide answers those questions clearly and honestly, so that you can make a fully informed decision before spending your money. What is a Natural Diamond? A natural diamond is a gemstone formed deep within the Earth’s mantle, approximately 150 to 200 kilometres below the surface. It takes between one billion and three billion years to form, under extreme heat and pressure that converts pure carbon into a crystalline structure — the hardest naturally occurring substance on the planet. Natural diamonds are brought closer to the surface through volcanic eruptions and are then mined from kimberlite rock formations. Their rarity, age, and geo...

  Every year, thousands of people across India spend their hard-earned money on gold jewellery, diamonds, and precious gemstones — without ever verifying what they are actually buying. A beautiful piece of jewellery does not always mean a genuine one. Gold can be under-karat. Diamonds can be lab-grown. Rubies can be glass-filled. This is where gemstone testing comes in. In this guide, we explain what gemstone testing is, why it matters, what the process involves, and how you can protect yourself as a buyer — whether you are in Mumbai, Delhi, Jaipur, or anywhere else across India. What Is Gemstone Testing?
