About this 0.3ct natural radiant diamond

This 0.3ct natural radiant sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5566756239. Listed at 14 retailers as of November 2, 2026, with prices from $253 to $789, a $535 spread on the same certified stone. MOH London lists it at $789. 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.
