About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG689520507 or 689520507. Listed at 10 retailers as of October 29, 2026, with prices from £278 to £2,209, a £1,932 spread on the same certified stone. Do Amore Diamonds lists it at £2,209. 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.
