About this 1.02ct natural round diamond

This 1.02ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by GIA 6201957519. Listed at 16 retailers as of November 5, 2026, with prices from $3,447 to $7,402, a $3,955 spread on the same certified stone. NZ Jewellers lists it at $7,402. 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.
