About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-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 7538863920. Listed at 25 retailers as of October 30, 2026, with prices from €1,872 to €4,941, a €3,069 spread on the same certified stone. NZ Jewellers lists it at €4,941. 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.
