About this 0.55ct natural cushion diamond

This 0.55ct natural cushion sits in the half to three-quarter 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 2517227030. Listed at 5 retailers as of November 4, 2026, with prices from HK$4,519 to HK$5,806, a HK$1,287 spread on the same certified stone. Blue Nile lists it at HK$5,806. 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.
