This 1.7ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 712558464. Listed at 14 retailers as of November 5, 2026, with prices from $13,291 to $22,204, a $8,913 spread on the same certified stone. NZ Jewellers lists it at $22,204. 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.
