About this 1.2ct natural marquise diamond

This 1.2ct 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 stated by the retailer rather than the lab and certified by GIA 6555329264. Listed at 17 retailers as of November 5, 2026, with prices from £3,222 to £6,445, a £3,223 spread on the same certified stone. NZ Jewellers lists it at £6,445. 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.
