Questions About Portuguese Cut Stone
  • 1stDibs ExpertOctober 12, 2021
    A princess-cut refers to a popular gemstone cut. A square, modified brilliant-cut stone with pointed corners, the princess cut is a variation on the round brilliant stone and came into fashion in the 1960s. This cut has maximum brilliance and, therefore, it is one of the most popular choices for engagement rings. Also, because of the square shape, more of the original gem is preserved, so there is less waste. Find a collection of vintage and antique princess-cut diamond jewelry on 1stDibs today.
