About this 0.99ct lab-grown round diamond

This 0.99ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG831691800 or 831691800. Listed at 3 retailers as of November 1, 2026, with prices from €295 to €828, a €533 spread on the same certified stone. Rare Carat lists it at €828. 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.
