About this 2.55ct natural radiant diamond

This 2.55ct 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 2155707222. Listed at 4 retailers as of November 2, 2026, with prices from €19,653 to €24,986, a €5,333 spread on the same certified stone. 77 Diamonds lists it at €24,986. 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.
