About this 0.87ct lab-grown marquise diamond

This 0.87ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG804625034 or 804625034. Listed at 23 retailers as of November 4, 2026, with prices from £353 to £2,028, a £1,675 spread on the same certified stone. Riddles Jewelry lists it at £2,028. 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.
