About this 0.66ct lab-grown round diamond

This 0.66ct lab-grown round 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 LG579376038 or 579376038. Listed at 21 retailers as of October 29, 2026, with prices from HK$1,773 to HK$8,868, a HK$7,095 spread on the same certified stone. MOH London lists it at HK$8,868. 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.
