About this 1.52ct natural heart diamond

This 1.52ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 809692078. Listed at 6 retailers as of October 30, 2026, with prices from £1,653 to £3,542, a £1,889 spread on the same certified stone. NZ Jewellers lists it at £3,542. 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.
