About this 0.63ct lab-grown marquise diamond

This 0.63ct 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 LG803617330 or 803617330. Listed at 21 retailers as of November 4, 2026, with prices from $653 to $3,686, a $3,034 spread on the same certified stone. Riddles Jewelry lists it at $3,686. 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.
