About this 0.66ct natural round diamond

This 0.66ct natural round sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6551035322. Listed at 6 retailers as of October 31, 2026, with prices from HK$6,724 to HK$8,262, a HK$1,538 spread on the same certified stone. Blue Nile lists it at HK$8,262. 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.
