About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6542605295. Listed at 12 retailers as of November 4, 2026, with prices from $739 to $1,817, a $1,078 spread on the same certified stone. MOH London lists it at $1,817. 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.
