About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 523283014. Listed at 13 retailers as of November 5, 2026, with prices from £1,227 to £3,605, a £2,378 spread on the same certified stone. NZ Jewellers lists it at £3,605. 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.
