GUIDANCE DIAMOND SHAPES CUSHION

round-stone-loop

Romantic - Sophisticated - Graceful

This shape is a blend of the classic and the contemporary diamond designs, developed to resemble the modern day round cut and the vintage mine cut. It sparkles less than the standard round shaped, however it has its beauty in its refined traditional look.

The cushion cut is special in the fact that it can come in a multitude of ratios, making it either square or rectangular. Additionally, the corners of this stone are rounded which allows for it to be paired with a woman with an active and trendy lifestyle.

Cushion cuts blend the energy of a round brilliant with the symmetry of a radiant cut. It's romantic appeal is reflected in its larger 58 facets and rounded, squared corners. Also known as the "pillow cut," the cushion cut has larger faceting, which augments the diamond's brilliance

The Hope Diamond—one of the world’s most famous—is a 45.54ct cushion cut.
