About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG838645107 or 838645107. Listed at 25 retailers as of October 30, 2026, with prices from HK$2,330 to HK$14,122, a HK$11,792 spread on the same certified stone. Brilliant Earth lists it at HK$14,122. 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.
