About this 3.01ct natural cushion diamond

This 3.01ct natural cushion sits in the three to five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1529597411. Listed at 6 retailers as of November 4, 2026, with prices from $17,517 to $26,893, a $9,376 spread on the same certified stone. GemTrove lists it at $26,893. 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.
