About this 0.9ct natural radiant diamond

This 0.9ct natural radiant sits in the just-under-one-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 6351106682. Listed at 16 retailers as of October 28, 2026, with prices from £2,097 to £4,425, a £2,328 spread on the same certified stone. Moon Ocean lists it at £4,425. 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.
