About this 0.81ct lab-grown round diamond

This 0.81ct lab-grown round sits in the just-under-one-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG821638035 or 821638035. Listed at 18 retailers as of October 29, 2026, with prices from €129 to €909, a €780 spread on the same certified stone. Reve Diamonds lists it at €909. 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.
