About this 0.57ct lab-grown marquise diamond

This 0.57ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817625563 or 817625563. Listed at 20 retailers as of October 30, 2026, with prices from HK$2,479 to HK$12,836, a HK$10,356 spread on the same certified stone. Riddles Jewelry lists it at HK$12,836. 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.
