About this 5.12ct natural cushion diamond

This 5.12ct natural cushion sits in the over five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6237513995. Listed at 10 retailers as of November 2, 2026, with prices from $45,568 to $83,256, a $37,688 spread on the same certified stone. MOH London lists it at $83,256. 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.
