About this 0.68ct lab-grown marquise diamond

This 0.68ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG651473398 or 651473398. Listed at 20 retailers as of October 29, 2026, with prices from £158 to £1,517, a £1,358 spread on the same certified stone. Do Amore Diamonds lists it at £1,517. 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.
