About this 1ct natural cushion diamond

This 1ct 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 5172418842. Listed at 16 retailers as of October 31, 2026, with prices from $3,953 to $8,608, a $4,655 spread on the same certified stone. MOH London lists it at $8,608. 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.
