About this 0.59ct lab-grown marquise diamond

This 0.59ct 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 LG735508327 or 735508327. Listed at 27 retailers as of October 29, 2026, with prices from £137 to £1,605, a £1,468 spread on the same certified stone. Do Amore Diamonds lists it at £1,605. 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.
