About this 2.2ct natural cushion diamond

This 2.2ct natural cushion sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551154930. Listed at 2 retailers as of October 30, 2026, with prices from $15,647 to $18,626, a $2,979 spread on the same certified stone. Blue Nile lists it at $18,626. 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.
