About this 1.09ct natural cushion diamond

This 1.09ct 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 2106631020. Listed at 4 retailers as of November 2, 2026, with prices from $2,572 to $4,059, a $1,487 spread on the same certified stone. MOH London lists it at $4,059. 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.
