About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5221729962. Listed at 13 retailers as of November 2, 2026, with prices from £1,926 to £4,285, a £2,359 spread on the same certified stone. NZ Jewellers lists it at £4,285. 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.
