About this 0.78ct lab-grown heart diamond

This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG727532786 or 727532786. Listed at 21 retailers as of October 30, 2026, with prices from HK$1,977 to HK$10,012, a HK$8,035 spread on the same certified stone. Reve Diamonds lists it at HK$10,012. 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.
