About this 1.05ct natural cushion diamond

This 1.05ct 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 2406919477. Listed at 19 retailers as of November 2, 2026, with prices from £1,126 to £2,358, a £1,232 spread on the same certified stone. MOH London lists it at £2,358. 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.
