About this 3.06ct natural cushion diamond

This 3.06ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551753387. Listed at 6 retailers as of October 31, 2026, with prices from $18,572 to $24,206, a $5,634 spread on the same certified stone. Blue Nile lists it at $24,206. 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.
