About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6372933941. Listed at 15 retailers as of November 5, 2026, with prices from £1,426 to £2,054, a £627 spread on the same certified stone. Yorxs lists it at £2,054. 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.
