About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 653410934. Listed at 15 retailers as of October 30, 2026, with prices from $3,750 to $7,360, a $3,610 spread on the same certified stone. NZ Jewellers lists it at $7,360. 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.
