About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 1425873376. Listed at 16 retailers as of October 30, 2026, with prices from $1,626 to $4,911, a $3,285 spread on the same certified stone. NZ Jewellers lists it at $4,911. 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.
