About this 0.56ct lab-grown marquise diamond

This 0.56ct 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 LG816603112 or 816603112. Listed at 20 retailers as of November 1, 2026, with prices from $175 to $1,054, a $879 spread on the same certified stone. Reve Diamonds lists it at $1,054. 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.
