About this 0.9ct natural round diamond

This 0.9ct natural round sits in the just-under-one-carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade and certified by GIA 1239815810. Listed at 14 retailers as of November 5, 2026, with prices from $1,046 to $4,380, a $3,334 spread on the same certified stone. NZ Jewellers lists it at $4,380. 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.
