About this 0.9ct natural round diamond

This 0.9ct natural round sits in the just-under-one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 603373700. Listed at 20 retailers as of November 5, 2026, with prices from $1,423 to $4,580, a $3,157 spread on the same certified stone. NZ Jewellers lists it at $4,580. 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.
