About this 0.9ct natural princess diamond

This 0.9ct natural princess sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6441800478. Listed at 12 retailers as of October 30, 2026, with prices from $1,378 to $3,877, a $2,499 spread on the same certified stone. Moon Ocean lists it at $3,877. 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.
