Old mine cut diamonds were cut for gas and candle light and omit a darker romantic sparkle. While the precision faceting of modern stone’s main objective is to refract as much white light as possible.  A 19th century diamond was cut to preserve as much weight as possible and often follow the same shape as the rough diamond crystal as it was pulled from the ground.
