About this 0.42ct natural princess diamond

This 0.42ct natural princess sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7542128651. Listed at 14 retailers as of November 5, 2026, with prices from $432 to $1,981, a $1,549 spread on the same certified stone. NZ Jewellers lists it at $1,981. 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.
