About this 0.4ct lab-grown marquise diamond

This 0.4ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG810613364 or 810613364. Listed at 16 retailers as of November 4, 2026, with prices from HK$1,122 to HK$6,477, a HK$5,355 spread on the same certified stone. MOH London lists it at HK$6,477. 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.
