About this 0.34ct lab-grown marquise diamond

This 0.34ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG798612256 or 798612256. Listed at 14 retailers as of October 30, 2026, with prices from $172 to $850, a $678 spread on the same certified stone. Taylor and Hart lists it at $850. 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.
