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 737518321. Listed at 4 retailers as of November 1, 2026, with prices from $4,892 to $10,226, a $5,334 spread on the same certified stone. NZ Jewellers lists it at $10,226. 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.
