About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2257755434. Listed at 7 retailers as of November 4, 2026, with prices from $2,525 to $3,699, a $1,175 spread on the same certified stone. Yorxs lists it at $3,699. 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.
