About this 5.13ct natural cushion diamond

This 5.13ct natural cushion sits in the over five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5556518051. Listed at 8 retailers as of November 1, 2026, with prices from $141,612 to $231,313, a $89,701 spread on the same certified stone. MOH London lists it at $231,313. 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.
