About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552572736. Listed at 11 retailers as of November 4, 2026, with prices from $3,749 to $7,130, a $3,381 spread on the same certified stone. Helzberg Diamonds lists it at $7,130. 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.
