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 G 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 1563575580. Listed at 6 retailers as of November 6, 2026, with prices from €2,442 to €3,399, a €957 spread on the same certified stone. Michael Trio lists it at €3,399. 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.
