About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 741568107. Listed at 6 retailers as of October 30, 2026, with prices from £1,442 to £3,293, a £1,850 spread on the same certified stone. NZ Jewellers lists it at £3,293. 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.
