About this 0.5ct natural heart diamond

This 0.5ct natural heart sits in the half to three-quarter carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 795659813. Listed at 14 retailers as of October 30, 2026, with prices from £317 to £1,319, a £1,002 spread on the same certified stone. NZ Jewellers lists it at £1,319. 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.
