About this 1ct natural radiant diamond

This 1ct 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 7421637627. Listed at 19 retailers as of October 29, 2026, with prices from $2,018 to $6,339, a $4,321 spread on the same certified stone. Adiamor lists it at $6,339. 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.
