About this 0.51ct lab-grown marquise diamond

This 0.51ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG807610401 or 807610401. Listed at 25 retailers as of November 3, 2026, with prices from $203 to $1,950, a $1,747 spread on the same certified stone. Do Amore Diamonds lists it at $1,950. 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.
