About this 3.21ct natural radiant diamond

This 3.21ct natural radiant sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1518980509. Listed at 19 retailers as of November 1, 2026, with prices from $63,268 to $113,653, a $50,385 spread on the same certified stone. MOH London lists it at $113,653. 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.
