About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552877413. Listed at 18 retailers as of November 4, 2026, with prices from £3,096 to £6,553, a £3,457 spread on the same certified stone. NZ Jewellers lists it at £6,553. 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.
