About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included) and certified by GIA 3565400574. Listed at 7 retailers as of October 31, 2026, with prices from $2,061 to $2,960, a $899 spread on the same certified stone. Blue Nile lists it at $2,960. 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.
