About this 1.28ct natural princess diamond

This 1.28ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6525991631. Listed at 2 retailers as of November 6, 2026. 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.
