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 7406670875. Listed at 9 retailers as of November 4, 2026, with prices from $1,652 to $3,192, a $1,540 spread on the same certified stone. Diamond Exchange Canada lists it at $3,192. 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.
