About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5563326530. Listed at 5 retailers as of October 29, 2026, with prices from HK$10,189 to HK$16,461, a HK$6,272 spread on the same certified stone. MOH London lists it at HK$16,461. 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.
