About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J 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 2547579757. Listed at 18 retailers as of November 3, 2026, with prices from £1,470 to £4,016, a £2,545 spread on the same certified stone. NZ Jewellers lists it at £4,016. 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.
