About this 2.5ct natural radiant diamond

This 2.5ct natural radiant sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1517970678. Listed at 13 retailers as of October 29, 2026, with prices from €20,373 to €36,754, a €16,380 spread on the same certified stone. MOH London lists it at €36,754. 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.
