About this 0.77ct lab-grown princess diamond

This 0.77ct lab-grown princess sits in the just-under-one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818671773 or 818671773. Listed at 20 retailers as of October 30, 2026, with prices from €307 to €1,374, a €1,067 spread on the same certified stone. Reve Diamonds lists it at €1,374. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
