About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5203042963. Listed at 16 retailers as of November 4, 2026, with prices from $4,149 to $9,244, a $5,095 spread on the same certified stone. NZ Jewellers lists it at $9,244. 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.
