This 1.02ct 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 835638840. Listed at 9 retailers as of October 30, 2026, with prices from £1,219 to £3,101, a £1,883 spread on the same certified stone. NZ Jewellers lists it at £3,101. 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.
