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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 425091447. Listed at 15 retailers as of November 5, 2026, with prices from $2,520 to $6,805, a $4,286 spread on the same certified stone. NZ Jewellers lists it at $6,805. 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.
