About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1417108422. Listed at 20 retailers as of November 1, 2026, with prices from £1,133 to £2,406, a £1,272 spread on the same certified stone. MOH London lists it at £2,406. 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.
