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 4, 2026, with prices from $3,315 to $6,212, a $2,897 spread on the same certified stone. MOH London lists it at $6,212. 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.
