About this 0.31ct lab-grown emerald diamond

This 0.31ct lab-grown emerald sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG719552900 or 719552900. Listed at 15 retailers as of October 29, 2026, with prices from HK$1,397 to HK$8,968, a HK$7,571 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$8,968. 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.
