About this 0.99ct lab-grown round diamond

This 0.99ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG831696225 or 831696225. Listed at 20 retailers as of October 31, 2026, with prices from HK$1,687 to HK$9,415, a HK$7,728 spread on the same certified stone. Brilliant Earth lists it at HK$9,415. 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.
