About this 0.8ct lab-grown marquise diamond

This 0.8ct lab-grown marquise 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 LG681520024 or 681520024. Listed at 2 retailers as of October 29, 2026, with prices from $340 to $1,210, a $870 spread on the same certified stone. Brilliant Earth lists it at $1,210. 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.
