About this 0.68ct lab-grown marquise diamond

This 0.68ct 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 LG696597782 or 696597782. Listed at 19 retailers as of October 30, 2026, with prices from £220 to £1,955, a £1,735 spread on the same certified stone. Do Amore Diamonds lists it at £1,955. 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.
