About this 1.53ct natural heart diamond

This 1.53ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 811606167. Listed at 13 retailers as of November 3, 2026, with prices from £5,352 to £10,357, a £5,005 spread on the same certified stone. NZ Jewellers lists it at £10,357. 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.
