About this 0.4ct lab-grown radiant diamond

This 0.4ct lab-grown radiant sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG799603132 or 799603132. Listed at 13 retailers as of October 29, 2026, with prices from HK$2,566 to HK$12,824, a HK$10,258 spread on the same certified stone. MOH London lists it at HK$12,824. 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.
