About this 0.64ct natural radiant diamond

This 0.64ct 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 1535744365. Listed at 10 retailers as of October 29, 2026, with prices from £490 to £863, a £373 spread on the same certified stone. GemTrove lists it at £863. 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.
