An Old Mine Cut Diamond is the ancestor of today’s cushion cut, most common in the Georgian and Victorian eras. Recognizable by its squarish outline with rounded corners, it has a small table, tall crown, deep pavilion, and a large culet. Unlike the rounder Old European Cut, the Old Mine’s hand-faceted proportions feel more rustic and organic, with a chunky facet pattern that creates a glowing, fire filled sparkle under candlelight. Its charm lies in its slightly irregular shape and antique character, making each stone truly one-of-a-kind.
