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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 3425030573. Listed at 5 retailers as of November 2, 2026, with prices from $1,135 to $2,489, a $1,354 spread on the same certified stone. MOH London lists it at $2,489. 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.
