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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG826603903 or 826603903. Listed at 4 retailers as of November 5, 2026, with prices from HK$7,822 to HK$10,435, a HK$2,613 spread on the same certified stone. Kay Jewelers lists it at HK$10,435. 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.
