What is
The Castlefield Cut™?

Castlefield Collection creates the most beautiful moissanite you'll ever see. Using only premium materials, our moissanite stones are cut to maximize their diamond-like clarity and sparkle - this is called the Castlefield Cut™. Even jewellers have a difficult time telling our moissanite apart from diamonds!

Why Choose Moissanite?

Moissanite is extremely clear, sparkly, virtually flawless - all at a very reasonable price. It is superior to diamonds in terms of brilliance and sparkle and is the second-hardest gemstone in the world. This makes it perfectly durable for everyday wear and can be passed down through generations.

Brilliance & Refraction

There is no stone on earth - natural or synthetic, that compares to the brilliance of moissanite. Moissanite is the world's most brilliant gemstone - meaning, it is exceptionally bright and sparkly!

Fire Dispersion

Moissanite measures at 2.4 times the fire of diamonds. This results in a beautifully iridescent sparkle. This fire can be either reduced or emphasized depending on the cut of the stone.

Clarity

All of our moissanite is graded at VVS+ or greater, meaning that it is free of any visible imperfections: virtually flawless. A clearer stone produces a brighter, more beautiful stone.

What is Moissanite?

Moissanite came from the stars. In 1893, French scientist Henri Moissan discovered beautiful natural moissanite inside a meteor crater. Today, natural moissanite is exceptionally rare - significantly rarer than diamonds.

Over time, lab-created moissanite was developed from the same material. It is perfect for engagement jewelry as it is highly durable, extremely beautiful, and both sustainable and eco-friendly.
