About this 0.31ct lab-grown round diamond

This 0.31ct lab-grown round sits in the sub-half-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG815670528 or 815670528. Listed at 5 retailers as of November 1, 2026, with prices from HK$1,004 to HK$6,287, a HK$5,283 spread on the same certified stone. MOH London lists it at HK$6,287. 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.
