About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556718194. Listed at 6 retailers as of November 1, 2026, with prices from £1,302 to £3,514, a £2,212 spread on the same certified stone. NZ Jewellers lists it at £3,514. 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.
