About this 0.42ct lab-grown emerald diamond

This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG662408844 or 662408844. Listed at 19 retailers as of October 30, 2026, with prices from HK$1,828 to HK$12,396, a HK$10,568 spread on the same certified stone. Kay Jewelers lists it at HK$12,396. 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.
