Aesthetically unique and modern, grey diamonds are available in lab grown diamonds and mined diamonds. In this blog, we look at what are grey diamonds, how they are formed, their key characteristics, and where to buy grey lab grown diamonds.

What are Grey Diamonds?

Grey diamonds have a grey hue. Their color can range from light silver to deep grey, charcoal, among other shades. Lab grown diamonds can be created in a variety of grey hues. Grey diamonds are sought after for their diamond color and unique aesthetics, and are priced for these characteristics.

How are Grey Diamonds Formed?

Grey diamonds are the result of the presence of hydrogen or boron during the process of formation that involves pressure and temperature. Lab grown diamonds of grey color are created by exposing the diamond seed to specific gasses under high temperature and pressure. Lab grown grey diamonds are created via two processes: CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature).
