About this 0.51ct lab-grown marquise diamond

This 0.51ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816662575 or 816662575. Listed at 17 retailers as of November 4, 2026, with prices from HK$1,820 to HK$10,144, a HK$8,324 spread on the same certified stone. Reve Diamonds lists it at HK$10,144. 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.
