About this 3.51ct natural radiant diamond

This 3.51ct 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 6502447772. Listed at 18 retailers, with prices from $37,811 to $71,717 at MOH London, a $33,906 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.
