About this 1.23ct natural heart diamond

This 1.23ct 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 762535068. Listed at 15 retailers as of November 3, 2026, with prices from $1,949 to $4,511, a $2,562 spread on the same certified stone. NZ Jewellers lists it at $4,511. 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.
