About this 1.02ct natural princess diamond

This 1.02ct natural princess sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566197662. Listed at 6 retailers as of October 31, 2026, with prices from $1,125 to $1,389, a $264 spread on the same certified stone. Blue Nile lists it at $1,389. 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.
