About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded I 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 7556868491. Listed at 6 retailers as of November 2, 2026, with prices from $28,703 to $44,902, a $16,199 spread on the same certified stone. MOH London lists it at $44,902. 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.
