Old Mine Brilliant Cushion Diamond Engagement Rings

An old mine brilliant cushion is an antique-style diamond cut with a cushion-like outline, softly rounded corners, and typically a high crown, smaller table, and bold facets. Traditional old mine cuts often have a visible culet, creating a distinctive appearance that recalls historic diamond cutting.

Modern cushion diamonds can have precise brilliant or crushed-ice faceting, while old mine styles are known for larger flashes of light and a softer, more individual pattern. An old mine brilliant often feels vintage and romantic, whereas a modern cushion can look more uniform or contemporary.

There is no single ideal ratio. Many old mine-style cushions have nearly square proportions, although some are more elongated or irregular. The beauty of the cut lies in the balance of its outline, facets, and personality, rather than meeting one exact measurement.

No. A genuine antique old mine diamond was cut in an earlier era, while a modern diamond can be newly fashioned with old mine-inspired proportions and facets. Both can offer an appealing vintage aesthetic, but their age and origin should be described accurately when selecting a stone.

Old mine brilliant cushions look beautiful in antique-inspired solitaires, delicate bezels, three-stone rings, and settings with milgrain or engraved details. A simple contemporary band can also create a striking contrast. At Engage Studio, the ring can be tailored to the diamond’s individual measurements and character.
