The Cushion Brellia is the world's first Cushion Hearts & Arrows diamond. The sheer brightness of the Brellia even surpasses most rounds. It was made to have such brightness to enhance the whiteness, emphasizing on the arrows. It proved to be the most brilliant Cushion diamond to have ever been cut.

Each Brellia diamond is cut and polished to the most exacting standards on earth. A standard known as "Super Ideal Cuts". It achieves the perfection of hearts and arrows with an AGS 000 cut grade, resulting in the highest brilliancy.
