About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 833655282. Listed at 14 retailers as of November 4, 2026, with prices from $5,800 to $11,587, a $5,787 spread on the same certified stone. NZ Jewellers lists it at $11,587. 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.
