About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565606932. Listed at 15 retailers as of November 5, 2026, with prices from $3,545 to $6,862, a $3,317 spread on the same certified stone. Helzberg Diamonds lists it at $6,862. 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.
