About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1559789936. Listed at 2 retailers as of October 29, 2026, with prices from £1,828 to £2,278, a £450 spread on the same certified stone. Yorxs lists it at £2,278. 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.
