About this 1.04ct natural cushion diamond

This 1.04ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3405607355. Listed at 6 retailers as of November 6, 2026, with prices from $1,736 to $3,137, a $1,402 spread on the same certified stone. Frank Darling lists it at $3,137. 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.
