About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567091917. Listed at 17 retailers as of November 4, 2026, with prices from £2,244 to £4,404, a £2,160 spread on the same certified stone. NZ Jewellers lists it at £4,404. 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.
