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 717560108. Listed at 14 retailers as of November 5, 2026, with prices from £1,346 to £3,609, a £2,262 spread on the same certified stone. NZ Jewellers lists it at £3,609. 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.
