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 6501517058. Listed at 12 retailers as of November 1, 2026, with prices from €2,221 to €4,349, a €2,128 spread on the same certified stone. MOH London lists it at €4,349. 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.
