About this 1ct natural marquise diamond

This 1ct 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 732579576. Listed at 16 retailers as of November 1, 2026, with prices from $5,114 to $10,095, a $4,981 spread on the same certified stone. NZ Jewellers lists it at $10,095. 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.
