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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 773616556. Listed at 16 retailers as of November 1, 2026, with prices from $2,326 to $5,415, a $3,089 spread on the same certified stone. NZ Jewellers lists it at $5,415. 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.
