About this 1ct natural cushion diamond

This 1ct 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 2364251633. Listed at 14 retailers as of November 4, 2026, with prices from $2,103 to $4,963, a $2,860 spread on the same certified stone. MOH London lists it at $4,963. 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.
