About this 1.8ct natural cushion diamond

This 1.8ct natural cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6521738910. Listed at 30 retailers as of October 29, 2026, with prices from $17,220 to $29,942, a $12,722 spread on the same certified stone. MOH London lists it at $29,942. 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.
