About this 0.42ct natural princess diamond

This 0.42ct natural princess sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566272945. Listed at 4 retailers as of November 4, 2026, with prices from $450 to $633, a $183 spread on the same certified stone. 77 Diamonds lists it at $633. 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.
