About this 1.7ct natural cushion diamond

This 1.7ct natural cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2558699385. Listed at 14 retailers as of November 1, 2026, with prices from $6,620 to $14,049, a $7,429 spread on the same certified stone. MOH London lists it at $14,049. 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.
