About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6491491128. Listed at 14 retailers as of November 4, 2026, with prices from $1,656 to $3,919, a $2,264 spread on the same certified stone. MOH London lists it at $3,919. 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.
