About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 170003090041. Listed at 2 retailers as of November 2, 2026, with prices from €1,392 to €1,651, a €259 spread on the same certified stone. 77 Diamonds lists it at €1,651. 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.
