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 very-good cut grade and certified by GIA 1278579531. Listed at 15 retailers as of November 5, 2026, with prices from $1,041 to $4,361, a $3,320 spread on the same certified stone. NZ Jewellers lists it at $4,361. 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.
