About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6372936927. Listed at 18 retailers as of November 6, 2026, with prices from £1,483 to £2,149, a £666 spread on the same certified stone. Yorxs lists it at £2,149. 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.
