About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 534240112. Listed at 12 retailers as of November 5, 2026, with prices from $2,950 to $6,826, a $3,876 spread on the same certified stone. NZ Jewellers lists it at $6,826. 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.
