About this 1.8ct natural cushion diamond

This 1.8ct natural cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6345641648. Listed at 22 retailers as of October 29, 2026, with prices from $15,076 to $26,856, a $11,780 spread on the same certified stone. MOH London lists it at $26,856. 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.
