About this 4.05ct natural radiant diamond

This 4.05ct natural radiant sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7558040912. Listed at 19 retailers as of November 1, 2026, with prices from €52,348 to €98,609, a €46,261 spread on the same certified stone. MOH London lists it at €98,609. 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.
