Cut: The Crucial "C"

What makes and original radiant cut diamond radiant?

Ordinary diamonds are cut to maximize their weight. Original Radiant Cut Diamonds are cut to maximize their beauty. Henry Grossbard's original innovative design combines the elegance of a squared shape with the brilliance of a round. Strategically angled cuts create virtual facets, exponentially increasing the scintillation – this is the sparkle that makes an engagement ring stand out!

Creating an Original Radiant Cut Diamond takes skill and vision. Each stone must be carefully cut to meet strict proportion standards. These proportion standards help ensure that your diamond is displayed to its best effect, strategically positioning the surface of the stone in a beautifully, visible way. Your diamond's cut quality will determine both how much it sparkles and how big your diamond will appear. A beautifully cut diamond that weighs 0.90 carat can look as big as an ordinary diamond weighing over 1.00 carat. The better cut diamond actually provides the best value, even if the inferior cut seems less expensive. Choosing an Original Radiant Cut Diamond means making a bigger impression at a better price.

The Grossbard family is committed to carries forward Henry Grossbard's legacy, using his secrets to maximize the impact of an Original Radiant Cut's virtual facets; the critical internal points where ordinary light is turned into dazzling sparkle. Each stone must pass a rigorous inspection to ensure it is truly beautiful enough to qualify as an Original Radiant Cut Diamond.

"A well cut radiant is one that spreads its carat weight and has the right life."
- Henry Grossbard
