About this 1.05ct natural radiant diamond

This 1.05ct natural radiant sits in the classic one-carat band, graded F 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 2215510853. Listed at 5 retailers as of October 28, 2026, with prices from $2,975 to $5,627, a $2,652 spread on the same certified stone. MOH London lists it at $5,627. 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.
