About this 1.09ct natural heart diamond

This 1.09ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 180000005407. Listed at 3 retailers as of November 3, 2026, with prices from €2,378 to €2,851, a €473 spread on the same certified stone. Yorxs lists it at €2,851. 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.
