About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 737553167. Listed at 11 retailers as of October 29, 2026, with prices from £965 to £2,184, a £1,218 spread on the same certified stone. MOH London lists it at £2,184. 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.
