About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2536131074. Listed at 8 retailers as of October 28, 2026, with prices from £16,789 to £21,315, a £4,526 spread on the same certified stone. Jared lists it at £21,315. 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.
