This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 814628555. Listed at 14 retailers as of November 5, 2026, with prices from $5,325 to $12,321, a $6,996 spread on the same certified stone. NZ Jewellers lists it at $12,321. 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.
