About this 1.64ct natural cushion diamond

This 1.64ct natural cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6545999324. Listed at 8 retailers as of November 2, 2026, with prices from $15,295 to $20,578, a $5,282 spread on the same certified stone. Jared lists it at $20,578. 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.
