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 I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6391576750. Listed at 8 retailers as of October 28, 2026, with prices from $6,157 to $8,907, a $2,750 spread on the same certified stone. Yorxs lists it at $8,907. 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.
