About this 0.8ct lab-grown marquise diamond

This 0.8ct 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 LG807610402 or 807610402. Listed at 29 retailers as of November 3, 2026, with prices from $385 to $3,421, a $3,036 spread on the same certified stone. Do Amore Diamonds lists it at $3,421. 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.
