1. What Is a Diamond?

A diamond is a crystalline form of carbon created under extreme pressure and temperature deep beneath the Earth’s surface. Diamonds are known for their unmatched hardness, extraordinary brilliance, and exceptional durability.

On the Mohs hardness scale, diamonds rank 10 out of 10, making them the hardest natural substance on Earth. This durability makes diamonds ideal for everyday jewelry like engagement rings, wedding bands, earrings, and luxury pendants.
