About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566555392. Listed at 10 retailers as of November 5, 2026, with prices from £2,878 to £5,919, a £3,041 spread on the same certified stone. NZ Jewellers lists it at £5,919. 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.
