About this 0.65ct natural radiant diamond

This 0.65ct natural radiant sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556390830. Listed at 4 retailers as of November 6, 2026, with prices from £442 to £1,218, a £776 spread on the same certified stone. Do Amore Diamonds lists it at £1,218. 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.
