About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7568358031. Listed at 22 retailers as of October 28, 2026, with prices from €18,721 to €33,789, a €15,068 spread on the same certified stone. MOH London lists it at €33,789. 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.
