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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7542486080. Listed at 7 retailers as of November 6, 2026, with prices from $1,253 to $1,790, a $537 spread on the same certified stone. GemTrove lists it at $1,790. 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.
