What is a Created Diamond?

Lab-created diamonds or lab-grown diamonds refer to diamonds that are created above ground. They are grown in labs with advanced technological processes that stimulate the same conditions under which mined diamonds develop beneath the earth’s crust.

Céleste diamonds are 100% real diamonds – the only difference is their origin. Every Céleste diamond is physically and chemically identical in composition to a diamond mined from the ground. Our state-of-the-art lab creates stones of exceptional quality – most are produced with clarities of VS or better.

We use two different methods for growing our diamonds - the high pressure, high temperature (HPHT) method and the chemical vapor deposition (CVD) method.


The high pressure, high temperature (HPHT) method begins with a small diamond seed. The seed is placed into a small piece of carbon and then pressurized. It is then exposed to a temperature of over 2700 degrees Fahrenheit. The carbon melts and forms into a diamond around the seed.


The chemical vapor deposition (CVD) method begins with a thin slice of diamond seed that is placed in a sealed chamber. The chamber is filled with carbon rich-gas which is then ionized into plasma using microwave technology. The molecular bonds in the gas is broken and the pure carbon slowly crystallizes and sticks to the diamond seed. This process takes between 6-10 weeks.

Sustainable Luxury

Celeste is commited to modernizing the diamond industry and working towards a more sustainable future. Miners move an average of 250 tons of earth for a single carat of diamond. Our diamonds are grown responsibly above-ground with limited impact to the environment.
