About this 0.73ct lab-grown radiant diamond

This 0.73ct lab-grown radiant 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 LG813608948 or 813608948. Listed at 13 retailers as of October 29, 2026, with prices from HK$1,640 to HK$8,744, a HK$7,104 spread on the same certified stone. Michael Trio lists it at HK$8,744. 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.
