About this 0.81ct natural round diamond

This 0.81ct 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 2447594385. Listed at 17 retailers as of October 30, 2026, with prices from $1,458 to $4,158, a $2,700 spread on the same certified stone. NZ Jewellers lists it at $4,158. 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.
