About this 6.15ct natural cushion diamond

This 6.15ct natural cushion sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2235837599. Listed at 14 retailers as of October 28, 2026, with prices from $274,548 to $338,553, a $64,005 spread on the same certified stone. Reve Diamonds lists it at $338,553. 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.
