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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG809664758 or 809664758. Listed at 9 retailers as of November 1, 2026, with prices from ₹24,677 to ₹81,964, a ₹57,288 spread on the same certified stone. MOH London lists it at ₹81,964. 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.
