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 October 30, 2026, with prices from $3,464 to $8,017, a $4,553 spread on the same certified stone. NZ Jewellers lists it at $8,017. 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.
