About this 1.56ct natural heart diamond

This 1.56ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 605315760. Listed at 15 retailers as of November 4, 2026, with prices from £3,227 to £6,446, a £3,219 spread on the same certified stone. NZ Jewellers lists it at £6,446. 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.
