This 1.86ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840629978 or 840629978. Listed at 18 retailers as of October 29, 2026, with prices from €357 to €3,554, a €3,196 spread on the same certified stone. Brilliant Earth lists it at €3,554. 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.
