About this 1.2ct natural round diamond

This 1.2ct 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 2225766661. Listed at 18 retailers as of November 5, 2026, with prices from $5,345 to $11,626, a $6,281 spread on the same certified stone. NZ Jewellers lists it at $11,626. 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.
