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 $1,574 to $4,946, a $3,372 spread on the same certified stone. Adiamor lists it at $4,946. 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.
