About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded H 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 6545978868. Listed at 3 retailers as of November 3, 2026, with prices from $33,001 to $39,504, a $6,503 spread on the same certified stone. Blue Nile lists it at $39,504. 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.
