About this 2.21ct natural radiant diamond

This 2.21ct 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 3505112593. Listed at 4 retailers as of November 3, 2026, with prices from £14,087 to £16,830, a £2,742 spread on the same certified stone. 77 Diamonds lists it at £16,830. 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.
