About this 4.05ct natural radiant diamond

This 4.05ct 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 6207533336. Listed at 7 retailers as of November 2, 2026, with prices from $62,627 to $78,979, a $16,353 spread on the same certified stone. 77 Diamonds lists it at $78,979. 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.
