About this 0.58ct lab-grown marquise diamond

This 0.58ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818658708 or 818658708. Listed at 19 retailers as of October 30, 2026, with prices from £228 to £1,065, a £837 spread on the same certified stone. Reve Diamonds lists it at £1,065. 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.
