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 603372201. Listed at 14 retailers as of November 4, 2026, with prices from £1,170 to £3,133, a £1,963 spread on the same certified stone. NZ Jewellers lists it at £3,133. 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.
