About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555372702. Listed at 3 retailers as of November 5, 2026, with prices from $15,809 to $18,933, a $3,125 spread on the same certified stone. Blue Nile lists it at $18,933. 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.
