About this 1.11ct natural radiant diamond

This 1.11ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 17159401. Listed at 3 retailers as of October 28, 2026, with prices from €2,841 to €4,227, a €1,386 spread on the same certified stone. 77 Diamonds lists it at €4,227. 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.
