About this 0.55ct lab-grown marquise diamond

This 0.55ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG719552729 or 719552729. Listed at 21 retailers as of November 4, 2026, with prices from HK$1,200 to HK$8,199, a HK$6,998 spread on the same certified stone. Reve Diamonds lists it at HK$8,199. 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.
