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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555133018. Listed at 2 retailers as of November 5, 2026, with prices from $1,961 to $2,755, a $795 spread on the same certified stone. Blue Nile lists it at $2,755. 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.
