About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1478070119. Listed at 8 retailers as of November 1, 2026, with prices from £1,421 to £3,584, a £2,162 spread on the same certified stone. NZ Jewellers lists it at £3,584. 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.
