About this 3.21ct natural radiant diamond

This 3.21ct natural radiant sits in the three to five 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 2235018932. Listed at 12 retailers, with prices from $33,575 to $61,294 at MOH London, a $27,719 spread on the same certified stone. 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.
