About this 0.53ct lab-grown radiant diamond

This 0.53ct 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 LG739588642 or 739588642. Listed at 12 retailers as of October 26, 2026, with prices from HK$1,608 to HK$8,828, a HK$7,220 spread on the same certified stone. MOH London lists it at HK$8,828. 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.
