About this 1.25ct natural heart diamond

This 1.25ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2245081371. Listed at 11 retailers as of November 5, 2026, with prices from €1,249 to €4,259, a €3,009 spread on the same certified stone. NZ Jewellers lists it at €4,259. 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.
