This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 660411191. Listed at 15 retailers as of November 4, 2026, with prices from $3,051 to $7,122, a $4,070 spread on the same certified stone. NZ Jewellers lists it at $7,122. 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.
