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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6234417850. Listed at 6 retailers as of October 29, 2026, with prices from £538 to £921, a £382 spread on the same certified stone. 77 Diamonds lists it at £921. 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.
