About this 0.85ct lab-grown marquise diamond

This 0.85ct 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 LG812621720 or 812621720. Listed at 19 retailers as of November 1, 2026, with prices from HK$3,201 to HK$10,184, a HK$6,983 spread on the same certified stone. Reve Diamonds lists it at HK$10,184. 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.
