About this 1.31ct natural heart diamond

This 1.31ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 260000075907. Listed at 5 retailers as of November 3, 2026, with prices from €1,973 to €4,209, a €2,236 spread on the same certified stone. NZ Jewellers lists it at €4,209. 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.
