About this 0.5ct lab-grown marquise diamond

This 0.5ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818663121 or 818663121. Listed at 19 retailers as of November 1, 2026, with prices from $474 to $2,341, a $1,867 spread on the same certified stone. Reve Diamonds lists it at $2,341. 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.
