The Most Painstakingly and Precisely Manufactured Round Diamond in Existence.
More than color or clarity, the cut of the diamond gives a diamond its brilliance and fire. Only a fraction of a percent of the world’s diamonds are cut to standards as rigid as the Private Reserve Diamond from the Diamond Cellar. It meets the requirements for GIA Excellent/Excellent and AGS Triple Zero, and displays the coveted Hearts and Arrows lighting effect. While other diamonds might meet only one of these standards, the Private Reserve Diamond from the Diamond Cellar meets all three.
