About this 3.09ct natural heart diamond

This 3.09ct natural heart sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6505779740. Listed at 14 retailers as of October 30, 2026, with prices from €19,802 to €27,970, a €8,168 spread on the same certified stone. NZ Jewellers lists it at €27,970. 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.
