About this 1.08ct natural cushion diamond

This 1.08ct natural cushion sits in the classic one-carat band, graded J 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 3545243171. Listed at 11 retailers as of November 2, 2026, with prices from £756 to £1,113, a £357 spread on the same certified stone. GemTrove lists it at £1,113. 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.
