About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2564209071. Listed at 21 retailers as of November 5, 2026, with prices from $4,199 to $9,668, a $5,470 spread on the same certified stone. NZ Jewellers lists it at $9,668. 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.
