About this 1.3ct natural heart diamond

This 1.3ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 700529089. Listed at 13 retailers as of October 30, 2026, with prices from £1,606 to £3,717, a £2,111 spread on the same certified stone. NZ Jewellers lists it at £3,717. 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.
