About this 1.06ct natural heart diamond

This 1.06ct natural heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 743512785. Listed at 13 retailers as of November 5, 2026, with prices from £1,987 to £4,459, a £2,471 spread on the same certified stone. NZ Jewellers lists it at £4,459. 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.
