About this 1.28ct natural heart diamond

This 1.28ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 738529041. Listed at 6 retailers as of November 2, 2026, with prices from £1,603 to £3,660, a £2,058 spread on the same certified stone. NZ Jewellers lists it at £3,660. 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.
