About this 0.78ct lab-grown marquise diamond

This 0.78ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG845658664 or 845658664. Listed at 17 retailers as of November 3, 2026, with prices from HK$3,892 to HK$20,138, a HK$16,246 spread on the same certified stone. MOH London lists it at HK$20,138. 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.
