About this 0.31ct lab-grown round diamond

This 0.31ct lab-grown round sits in the sub-half-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG741573324 or 741573324. Listed at 16 retailers as of October 29, 2026, with prices from HK$706 to HK$7,174, a HK$6,468 spread on the same certified stone. MOH London lists it at HK$7,174. 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.
