About this 1.04ct natural cushion diamond

This 1.04ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558417159. Listed at 17 retailers as of November 1, 2026, with prices from £1,374 to £3,137, a £1,764 spread on the same certified stone. MOH London lists it at £3,137. 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.
