Based in India's diamond capital, we bring together cutting-edge technology and decades of gemological expertise to produce diamonds that are chemically, physically, and optically identical to mined diamonds — at a fraction of the cost.

​

Whether you need round brilliants, fancy cuts, or custom shapes, Nishal Gems delivers consistent quality with every single stone.

What is a Lab Grown Diamond?

A lab grown diamond is a real diamond — created in a controlled laboratory environment using advanced technology instead of being mined from the earth.

​

The two main methods are:

  • CVD (Chemical Vapor Deposition): Carbon gases are used to grow a diamond layer by layer inside a chamber

  • HPHT (High Pressure High Temperature): Diamonds are grown by replicating the extreme conditions found deep in the earth

 

Both methods produce 100% real diamonds with the same fire, sparkle, and durability as natural diamonds. The difference? Lab grown diamonds are conflict-free, eco-friendly, and up to 70% more affordable.
