This 1.37ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 810645514. Listed at 16 retailers as of November 5, 2026, with prices from $4,587 to $10,515, a $5,928 spread on the same certified stone. NZ Jewellers lists it at $10,515. 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.
