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) and certified by IGI 839666881. Listed at 8 retailers as of November 1, 2026, with a 94% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
