About this 0.53ct lab-grown marquise diamond

This 0.53ct 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 LG818663124 or 818663124. Listed at 19 retailers as of October 30, 2026, with prices from £210 to £1,015, a £805 spread on the same certified stone. Reve Diamonds lists it at £1,015. 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.
