About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2538900381. Listed at 21 retailers as of November 4, 2026, with prices from HK$3,558 to HK$15,205, a HK$11,646 spread on the same certified stone. NZ Jewellers lists it at HK$15,205. 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.
