About this 0.51ct lab-grown emerald diamond

This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG680563328 or 680563328. Listed at 12 retailers as of October 29, 2026, with prices from HK$2,275 to HK$11,220, a HK$8,945 spread on the same certified stone. MOH London lists it at HK$11,220. 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.
