About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561434788. Listed at 17 retailers as of November 4, 2026, with prices from $8,701 to $15,402, a $6,701 spread on the same certified stone. MOH London lists it at $15,402. 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.
