About this 0.99ct lab-grown heart diamond

This 0.99ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG594338252 or 594338252. Listed at 20 retailers as of October 27, 2026, with prices from HK$1,993 to HK$12,238, a HK$10,246 spread on the same certified stone. Brilliant Earth lists it at HK$12,238. 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.
