About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 801637997. Listed at 17 retailers as of November 1, 2026, with prices from $1,621 to $5,607, a $3,986 spread on the same certified stone. NZ Jewellers lists it at $5,607. 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.
