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 2566283634. Listed at 14 retailers as of October 30, 2026, with prices from $1,792 to $4,738, a $2,945 spread on the same certified stone. NZ Jewellers lists it at $4,738. 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.
