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 LG816603116 or 816603116. Listed at 19 retailers as of October 30, 2026, with prices from £213 to £1,023, a £810 spread on the same certified stone. Reve Diamonds lists it at £1,023. 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.
