About this 2.4ct natural radiant diamond

This 2.4ct natural radiant sits in the two to three 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 6542319990. Listed at 21 retailers as of October 30, 2026, with prices from $19,281 to $36,382, a $17,101 spread on the same certified stone. NZ Jewellers lists it at $36,382. 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.
