About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 689598816. Listed at 17 retailers as of November 4, 2026, with prices from £1,166 to £3,120, a £1,954 spread on the same certified stone. NZ Jewellers lists it at £3,120. 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.
