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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551868509. Listed at 16 retailers as of November 1, 2026, with prices from €19,432 to €34,536, a €15,104 spread on the same certified stone. MOH London lists it at €34,536. 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.
