About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1549375027. Listed at 20 retailers as of November 4, 2026, with prices from $2,394 to $5,497, a $3,102 spread on the same certified stone. MOH London lists it at $5,497. 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.
