About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 791655614. Listed at 15 retailers as of November 4, 2026, with prices from $748 to $2,541, a $1,793 spread on the same certified stone. NZ Jewellers lists it at $2,541. 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.
