About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1515308553. Listed at 8 retailers as of November 4, 2026, with prices from $3,555 to $7,860, a $4,305 spread on the same certified stone. MOH London lists it at $7,860. 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.
