About this 0.5ct lab-grown marquise diamond

This 0.5ct 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 LG845658735 or 845658735. Listed at 10 retailers as of November 5, 2026, with prices from $213 to $1,105, a $892 spread on the same certified stone. MOH London lists it at $1,105. 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.
