This 1.31ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 632436360. Listed at 11 retailers as of October 30, 2026, with prices from $6,091 to $12,063, a $5,972 spread on the same certified stone. NZ Jewellers lists it at $12,063. 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.
