About this 1.6ct natural cushion diamond

This 1.6ct natural cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6455756116. Listed at 9 retailers as of November 1, 2026, with prices from $8,116 to $10,639, a $2,523 spread on the same certified stone. Yorxs lists it at $10,639. 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.
