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 1395672785. Listed at 18 retailers as of November 5, 2026, with prices from $1,297 to $4,280, a $2,983 spread on the same certified stone. NZ Jewellers lists it at $4,280. 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.
