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 31, 2026, with prices from HK$1,875 to HK$6,669, a HK$4,794 spread on the same certified stone. Brilliant Earth lists it at HK$6,669. 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.
