About this 5.23ct natural cushion diamond

This 5.23ct 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 5212821506. Listed at 4 retailers as of November 2, 2026, with prices from $73,762 to $93,479, a $19,717 spread on the same certified stone. 77 Diamonds lists it at $93,479. 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.
