About this 1ct natural princess diamond

This 1ct 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 6511672173. Listed at 14 retailers as of October 30, 2026, with prices from $1,203 to $2,903, a $1,700 spread on the same certified stone. Diamond Exchange Canada lists it at $2,903. 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.
