About this 0.82ct lab-grown marquise diamond

This 0.82ct lab-grown marquise sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG814642911 or 814642911. Listed at 26 retailers as of November 2, 2026, with prices from £178 to £1,394, a £1,215 spread on the same certified stone. Do Amore Diamonds lists it at £1,394. 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.
