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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557150329. Listed at 18 retailers as of November 1, 2026, with prices from $25,971 to $45,613, a $19,642 spread on the same certified stone. MOH London lists it at $45,613. 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.
