About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566503696. Listed at 9 retailers as of November 1, 2026, with prices from $23,289 to $38,349, a $15,060 spread on the same certified stone. MOH London lists it at $38,349. 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.
