Old Mine

Old Mine cut diamonds date back to the 1830's and were common up until the turn of the century. A mine cut diamond is shaped into a high crown with a small table, a round to somewhat rectangular girdle, a deep pavilion and a large faceted culet. The cut was the earliest form of the brilliant cut, which means that the diamond was cut to allow the stone to sparkle under even the dimmest candle light of the era. The cut is also known as Old Miner cut, Triple Brilliant cut, or Peruzzi cut.

The Old Mine cut resembles the modern cushion cut. Some jewelry experts consider the cushion cut the modern version of the mine cut. The difference is that mine cut diamonds are slightly more rounded and do not have a clear rectangular or cushion shape.
