About this 0.51ct lab-grown emerald diamond

This 0.51ct lab-grown emerald 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 LG794666482 or 794666482. Listed at 19 retailers as of October 29, 2026, with prices from HK$1,200 to HK$7,015, a HK$5,814 spread on the same certified stone. MOH London lists it at HK$7,015. 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.
