About this 0.81ct natural cushion diamond

This 0.81ct natural cushion sits in the just-under-one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2376721685. Listed at 20 retailers as of November 2, 2026, with prices from £852 to £1,884, a £1,033 spread on the same certified stone. MOH London lists it at £1,884. 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.
