About this 1.18ct natural cushion diamond

This 1.18ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6223810020. Listed at 12 retailers as of November 7, 2026, with prices from $4,860 to $9,016, a $4,157 spread on the same certified stone. MOH London lists it at $9,016. 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.
