About this 0.9ct natural princess diamond

This 0.9ct natural princess sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6451039940. Listed at 22 retailers as of October 27, 2026, with prices from $1,915 to $5,338, a $3,423 spread on the same certified stone. NZ Jewellers lists it at $5,338. 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.
