About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 750555460. Listed at 14 retailers as of November 4, 2026, with prices from £3,089 to £6,171, a £3,082 spread on the same certified stone. NZ Jewellers lists it at £6,171. 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.
