About this 1ct natural heart diamond

This 1ct 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 447090724. Listed at 14 retailers as of November 5, 2026, with prices from $4,548 to $8,926, a $4,378 spread on the same certified stone. NZ Jewellers lists it at $8,926. 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.
