About this 0.66ct natural cushion diamond

This 0.66ct natural cushion sits in the half to three-quarter carat band, graded H colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6237993665. Listed at 6 retailers as of November 1, 2026, with prices from $870 to $1,461, a $590 spread on the same certified stone. Yorxs lists it at $1,461. 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.
