About this 0.4ct natural radiant diamond

This 0.4ct natural radiant sits in the sub-half-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6431618648. Listed at 5 retailers as of October 28, 2026, with prices from £641 to £1,215, a £574 spread on the same certified stone. MOH London lists it at £1,215. 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.
