About this 0.81ct lab-grown cushion diamond

This 0.81ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG807613906 or 807613906. Listed at 11 retailers as of October 30, 2026, with prices from HK$3,688 to HK$22,191, a HK$18,503 spread on the same certified stone. MOH London lists it at HK$22,191. 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.
