About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG790684977 or 790684977. Listed at 26 retailers as of October 31, 2026, with prices from £180 to £1,545, a £1,365 spread on the same certified stone. Do Amore Diamonds lists it at £1,545. 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.
