About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round 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 and certified by IGI LG846661635 or 846661635. Listed at 9 retailers as of November 1, 2026, with prices from HK$1,451 to HK$8,529, a HK$7,078 spread on the same certified stone. MOH London lists it at HK$8,529. 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.
