About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG831697397 or 831697397. Listed at 4 retailers as of October 29, 2026, with prices from HK$10,356 to HK$11,918, a HK$1,561 spread on the same certified stone. Loose Grown Diamond lists it at HK$11,918. 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.
