About this 1ct natural princess diamond

This 1ct natural princess sits in the classic one-carat band, graded I 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 6451896126. Listed at 15 retailers as of October 30, 2026, with prices from $2,046 to $6,276, a $4,229 spread on the same certified stone. NZ Jewellers lists it at $6,276. 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.
