About this 1.09ct natural round diamond

This 1.09ct natural round sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 6137467531. Listed at 5 retailers as of October 31, 2026, with prices from $15,893 to $21,899, a $6,005 spread on the same certified stone. Yorxs lists it at $21,899. 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.
