This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 608304917. Listed at 17 retailers as of November 5, 2026, with prices from $6,534 to $15,138, a $8,605 spread on the same certified stone. NZ Jewellers lists it at $15,138. 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.
