About this 0.39ct natural radiant diamond

This 0.39ct natural radiant sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5211746914. Listed at 7 retailers as of November 4, 2026, with prices from £265 to £667, a £402 spread on the same certified stone. MOH London lists it at £667. 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.
