About this 3.51ct natural radiant diamond

This 3.51ct natural radiant sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2507507642. Listed at 9 retailers as of October 28, 2026, with prices from $40,862 to $51,739, a $10,876 spread on the same certified stone. Jared lists it at $51,739. 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.
