About this 1.8ct natural cushion diamond

This 1.8ct natural cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556707671. Listed at 9 retailers as of November 1, 2026, with prices from $7,989 to $15,178, a $7,189 spread on the same certified stone. With Clarity lists it at $15,178. 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.
