About this 2.5ct natural cushion diamond

This 2.5ct natural cushion sits in the two to three carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566127046. Listed at 2 retailers as of October 30, 2026, with prices from $18,569 to $21,894, a $3,325 spread on the same certified stone. Blue Nile lists it at $21,894. 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.
