About this 0.55ct lab-grown radiant diamond

This 0.55ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG812620705 or 812620705. Listed at 20 retailers as of November 4, 2026, with prices from HK$1,263 to HK$7,971, a HK$6,708 spread on the same certified stone. Reve Diamonds lists it at HK$7,971. 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.
