About this 1.02ct natural cushion diamond

This 1.02ct 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 1388878561. Listed at 13 retailers as of October 29, 2026, with prices from $2,369 to $5,650, a $3,281 spread on the same certified stone. MOH London lists it at $5,650. 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.
