About this 1ct natural marquise diamond

This 1ct 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 7552554949. Listed at 25 retailers as of October 30, 2026, with prices from £1,771 to £4,023, a £2,252 spread on the same certified stone. NZ Jewellers lists it at £4,023. 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.
