This 1.65ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 550264414. Listed at 14 retailers as of October 30, 2026, with prices from $5,757 to $11,501, a $5,744 spread on the same certified stone. NZ Jewellers lists it at $11,501. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
