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 LG799697362 or 799697362. Listed at 27 retailers as of October 30, 2026, with prices from £149 to £1,433, a £1,284 spread on the same certified stone. Do Amore Diamonds lists it at £1,433. 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.
