About this 4.01ct natural radiant diamond

This 4.01ct natural radiant sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1523642911. Listed at 3 retailers as of November 1, 2026, with prices from $51,428 to $65,513, a $14,085 spread on the same certified stone. Ritani lists it at $65,513. 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.
