About this 0.55ct lab-grown heart diamond

This 0.55ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG812620870 or 812620870. Listed at 18 retailers as of October 28, 2026, with prices from HK$1,703 to HK$9,222, a HK$7,519 spread on the same certified stone. Reve Diamonds lists it at HK$9,222. 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.
