About this 1.18ct natural cushion diamond

This 1.18ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556309483. Listed at 4 retailers as of November 4, 2026, with prices from $3,088 to $5,846, a $2,758 spread on the same certified stone. MOH London lists it at $5,846. 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.
