About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2504530256. Listed at 16 retailers as of October 30, 2026, with prices from £1,714 to £3,425, a £1,710 spread on the same certified stone. MOH London lists it at £3,425. 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.
