About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-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 6551519300. Listed at 15 retailers as of October 30, 2026, with prices from $1,879 to $6,099, a $4,220 spread on the same certified stone. NZ Jewellers lists it at $6,099. 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.
