About this 0.99ct lab-grown marquise diamond

This 0.99ct 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 LG677525084 or 677525084. Listed at 29 retailers as of November 4, 2026, with prices from $475 to $3,783, a $3,307 spread on the same certified stone. Do Amore Diamonds lists it at $3,783. 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.
