About this 0.45ct natural round diamond

This 0.45ct natural round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1545578277. Listed at 17 retailers as of November 2, 2026, with prices from HK$3,707 to HK$13,841, a HK$10,134 spread on the same certified stone. NZ Jewellers lists it at HK$13,841. 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.
