About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 345829257. Listed at 15 retailers as of October 30, 2026, with prices from €1,097 to €2,901, a €1,804 spread on the same certified stone. NZ Jewellers lists it at €2,901. 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.
