About this 1.31ct natural round diamond

This 1.31ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6372528755. Listed at 11 retailers as of November 1, 2026, with prices from $2,127 to $6,131, a $4,004 spread on the same certified stone. NZ Jewellers lists it at $6,131. 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.
