About this 0.78ct natural cushion diamond

This 0.78ct natural cushion 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 stated by the retailer rather than the lab and certified by GIA 2557404485. Listed at 7 retailers as of November 3, 2026, with prices from HK$10,867 to HK$14,168, a HK$3,301 spread on the same certified stone. GemTrove lists it at HK$14,168. 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.
