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 IGI 644426861. Listed at 12 retailers as of October 31, 2026, with prices from HK$28,418 to HK$49,631, a HK$21,213 spread on the same certified stone. Diamond Quarter lists it at HK$49,631. 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.
