About this 0.51ct lab-grown asscher diamond

This 0.51ct lab-grown asscher 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 LG655445393 or 655445393. Listed at 2 retailers as of October 31, 2026, with prices from HK$1,248 to HK$5,748, a HK$4,501 spread on the same certified stone. Diamond Quarter lists it at HK$5,748. 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.
