About this 0.8ct natural cushion diamond

This 0.8ct 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 6301881954. Listed at 15 retailers as of November 4, 2026, with prices from $1,340 to $3,318, a $1,977 spread on the same certified stone. MOH London lists it at $3,318. 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.
