About this 1.22ct natural radiant diamond

This 1.22ct natural radiant sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1555765931. Listed at 14 retailers as of November 5, 2026, with prices from $4,378 to $8,128, a $3,750 spread on the same certified stone. Helzberg Diamonds lists it at $8,128. 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.
