About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded D 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 1558343406. Listed at 14 retailers as of November 4, 2026, with prices from $1,508 to $3,560, a $2,052 spread on the same certified stone. MOH London lists it at $3,560. 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.
