About this 1.2ct natural radiant diamond

This 1.2ct 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 2245004878. Listed at 12 retailers as of October 31, 2026, with prices from $3,299 to $6,157, a $2,858 spread on the same certified stone. Helzberg Diamonds lists it at $6,157. 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.
