This 1.71ct 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 LG831694267 or 831694267. Listed at 11 retailers as of October 31, 2026, with prices from €382 to €1,586, a €1,204 spread on the same certified stone. Brilliance lists it at €1,586. 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.
