About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2233657276. Listed at 27 retailers as of October 30, 2026, with prices from $5,873 to $12,970, a $7,098 spread on the same certified stone. NZ Jewellers lists it at $12,970. 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.
