About this 0.81ct lab-grown round diamond

This 0.81ct 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 LG784669220 or 784669220. Listed at 3 retailers as of October 27, 2026, with prices from $195 to $680, a $485 spread on the same certified stone. Brilliant Earth lists it at $680. 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.
