About this 1.8ct natural cushion diamond

This 1.8ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-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 1545597142. Listed at 10 retailers as of October 29, 2026, with prices from $5,014 to $10,455, a $5,441 spread on the same certified stone. MOH London lists it at $10,455. 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.
