This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 816643921. Listed at 11 retailers as of November 2, 2026, with prices from $4,389 to $10,691, a $6,303 spread on the same certified stone. NZ Jewellers lists it at $10,691. 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.
