About this 0.8ct lab-grown cushion diamond

This 0.8ct 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 LG835656592 or 835656592. Listed at 19 retailers as of October 30, 2026, with prices from HK$4,590 to HK$25,924, a HK$21,334 spread on the same certified stone. Riddles Jewelry lists it at HK$25,924. 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.
