About this 0.45ct lab-grown marquise diamond

This 0.45ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG807610160 or 807610160. Listed at 13 retailers as of October 31, 2026, with prices from €242 to €1,264, a €1,022 spread on the same certified stone. Taylor and Hart lists it at €1,264. 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.
