About this 0.56ct natural radiant diamond

This 0.56ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566530667. Listed at 3 retailers as of November 4, 2026, with prices from £489 to £587, a £99 spread on the same certified stone. Brilliance lists it at £587. 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.
