About this 30.13ct natural radiant diamond

This 30.13ct natural radiant sits in the over five carat band, graded FANCY colour (tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2175466619. Listed at 6 retailers as of October 25, 2026, with prices from $391,690 to $583,890, a $192,200 spread on the same certified stone. Calavera New York lists it at $583,890. 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.
