About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5563659544. Listed at 13 retailers as of November 5, 2026, with prices from £2,347 to £4,910, a £2,563 spread on the same certified stone. NZ Jewellers lists it at £4,910. 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.
