About this 1ct natural cushion diamond

This 1ct 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 1545557378. Listed at 16 retailers as of October 25, 2026, with prices from $1,591 to $3,738, a $2,146 spread on the same certified stone. MOH London lists it at $3,738. 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.
