About this 0.98ct lab-grown marquise diamond

This 0.98ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818659102 or 818659102. Listed at 20 retailers as of October 28, 2026, with prices from $294 to $1,940, a $1,646 spread on the same certified stone. Rare Carat lists it at $1,940. 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.
