About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5453114807. Listed at 3 retailers as of October 31, 2026, with prices from $1,411 to $2,029, a $618 spread on the same certified stone. Yorxs lists it at $2,029. 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.
