About this 1.09ct natural cushion diamond

This 1.09ct natural cushion sits in the classic 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 6561755163. Listed at 5 retailers as of November 1, 2026, with prices from $1,239 to $2,171, a $932 spread on the same certified stone. 77 Diamonds lists it at $2,171. 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.
