About this 3.03ct lab-grown cushion diamond

This 3.03ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818640129 or 818640129. Listed at 22 retailers as of October 28, 2026, with prices from €1,675 to €7,403, a €5,729 spread on the same certified stone. Brilliant Earth lists it at €7,403. 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.
