About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2564300221. Listed at 22 retailers as of October 30, 2026, with prices from HK$4,720 to HK$20,014, a HK$15,294 spread on the same certified stone. NZ Jewellers lists it at HK$20,014. 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.
