About this 0.7ct lab-grown marquise diamond

This 0.7ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG745526367 or 745526367. Listed at 21 retailers as of October 30, 2026, with prices from £226 to £2,008, a £1,781 spread on the same certified stone. Do Amore Diamonds lists it at £2,008. 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.
