About this 3.5ct natural radiant diamond

This 3.5ct 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 6491121733. Listed at 23 retailers, with prices from $38,215 to $70,523 at MOH London, a $32,308 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.
