About this 0.8ct natural round diamond

This 0.8ct natural round sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6422966603. Listed at 15 retailers as of November 5, 2026, with prices from $1,338 to $5,643, a $4,304 spread on the same certified stone. NZ Jewellers lists it at $5,643. 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.
