About this 0.99ct lab-grown radiant diamond

This 0.99ct lab-grown radiant sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG770617411 or 770617411. Listed at 17 retailers as of October 27, 2026, with prices from HK$1,993 to HK$17,733, a HK$15,740 spread on the same certified stone. Do Amore Diamonds lists it at HK$17,733. 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.
