About this 0.77ct natural round diamond

This 0.77ct natural round sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1555191817. Listed at 18 retailers as of November 2, 2026, with prices from HK$25,845 to HK$46,833, a HK$20,988 spread on the same certified stone. MOH London lists it at HK$46,833. 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.
