About this 0.55ct lab-grown round diamond

This 0.55ct lab-grown round 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 LG790639864 or 790639864. Listed at 15 retailers as of October 30, 2026, with prices from HK$1,028 to HK$10,522, a HK$9,494 spread on the same certified stone. MOH London lists it at HK$10,522. 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.
