About this 1.01ct natural heart diamond

This 1.01ct 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 508118625. Listed at 14 retailers as of November 5, 2026, with prices from £1,156 to £3,400, a £2,244 spread on the same certified stone. NZ Jewellers lists it at £3,400. 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.
