About this 5.03ct natural cushion diamond

This 5.03ct natural cushion sits in the over five carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6243012246. Listed at 6 retailers as of October 31, 2026, with prices from $60,564 to $77,848, a $17,284 spread on the same certified stone. Blue Nile lists it at $77,848. 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.
