About this 0.68ct lab-grown marquise diamond

This 0.68ct 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 LG660435735 or 660435735. Listed at 22 retailers as of November 2, 2026, with prices from HK$1,459 to HK$18,908, a HK$17,449 spread on the same certified stone. Do Amore Diamonds lists it at HK$18,908. 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.
