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 H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2456078492. Listed at 3 retailers as of November 2, 2026, with prices from €2,758 to €4,163, a €1,405 spread on the same certified stone. 77 Diamonds lists it at €4,163. 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.
