This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 801638806. Listed at 19 retailers as of October 30, 2026, with prices from $10,086 to $20,372, a $10,286 spread on the same certified stone. NZ Jewellers lists it at $20,372. 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.
