About this 2.5ct natural radiant diamond

This 2.5ct 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 1517104045. Listed at 9 retailers as of October 31, 2026, with prices from $22,338 to $30,710, a $8,372 spread on the same certified stone. Yorxs lists it at $30,710. 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.
