About this 0.31ct natural cushion diamond

This 0.31ct natural cushion 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 stated by the retailer rather than the lab and certified by GIA 6545318913. Listed at 6 retailers as of November 1, 2026, with prices from HK$3,977 to HK$7,423, a HK$3,446 spread on the same certified stone. MOH London lists it at HK$7,423. 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.
