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 1418861366. Listed at 20 retailers as of October 29, 2026, with prices from $4,920 to $10,361, a $5,441 spread on the same certified stone. MOH London lists it at $10,361. 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.
