About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555748821. Listed at 5 retailers as of November 4, 2026, with prices from £852 to £1,092, a £239 spread on the same certified stone. GemTrove lists it at £1,092. 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.
