About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6371936830. Listed at 15 retailers as of November 4, 2026, with prices from $3,300 to $4,750, a $1,450 spread on the same certified stone. Yorxs lists it at $4,750. 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.
