About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7518634949. Listed at 17 retailers as of October 29, 2026, with prices from £994 to £2,390, a £1,397 spread on the same certified stone. MOH London lists it at £2,390. 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.
