About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6541933009. Listed at 7 retailers as of November 3, 2026, with prices from £2,762 to £5,272, a £2,510 spread on the same certified stone. NZ Jewellers lists it at £5,272. 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.
