About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2506019211. Listed at 6 retailers as of November 1, 2026, with prices from £5,148 to £7,609, a £2,461 spread on the same certified stone. MOH London lists it at £7,609. 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.
