About this 1.13ct natural cushion diamond

This 1.13ct natural cushion sits in the classic 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 7443229255. Listed at 7 retailers as of October 31, 2026, with prices from $3,747 to $4,349, a $602 spread on the same certified stone. The Diamond Guys lists it at $4,349. 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.
