Modern stones cut in the old mine style to meet demand for an antique look are pricing well below genuine antique-cut stones, and the gap between the two has widened.

  • An old mine cut is a specific historic cutting style with a small table, high crown and cushion-like outline; a genuine antique is a stone actually cut in that era, while a reproduction is a modern stone cut to imitate the look.
  • Demand tied to antique cushion and old European cuts has pulled buyers toward the style faster than the supply of genuine antique-cut stones can meet, which has pushed more buyers toward reproductions.
  • Because reproductions can be cut from any suitable rough, cutters have scaled up supply, and prices have not kept pace with the genuine-antique segment, widening the gap between the two.

If the history of the cut matters to you as much as the look, ask specifically whether a stone is a genuine antique cut or a modern reproduction — the two are graded and priced differently even when they look similar to the eye.
