About this 2.5ct natural radiant diamond

This 2.5ct 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 2225826209. Listed at 19 retailers as of November 2, 2026. 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.
