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 SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6442667694. Listed at 17 retailers as of November 4, 2026, with prices from $1,704 to $5,112, a $3,408 spread on the same certified stone. NZ Jewellers lists it at $5,112. 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.
