About this 1.03ct lab-grown oval diamond

This 1.03ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG850682250 or 850682250. Listed at 6 retailers as of October 29, 2026, with prices from €285 to €1,275, a €990 spread on the same certified stone. Brilliant Earth lists it at €1,275. 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.
