About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555724656. Listed at 8 retailers as of November 1, 2026, with prices from £1,701 to £2,024, a £322 spread on the same certified stone. GemTrove lists it at £2,024. 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.
