About this 1.04ct natural radiant diamond

This 1.04ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6512221437. Listed at 6 retailers as of November 4, 2026, with prices from £1,487 to £1,782, a £295 spread on the same certified stone. Blue Nile lists it at £1,782. 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.
