About this 0.25ct natural cushion diamond

This 0.25ct natural cushion sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555421439. Listed at 4 retailers as of October 29, 2026, with prices from $307 to $815, a $508 spread on the same certified stone. Yorxs lists it at $815. 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.
