About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded I 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 3395812559. Listed at 22 retailers as of November 4, 2026, with prices from £1,836 to £3,993, a £2,157 spread on the same certified stone. MOH London lists it at £3,993. 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.
