About this 0.59ct lab-grown marquise diamond

This 0.59ct 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 LG778617169 or 778617169. Listed at 10 retailers as of October 30, 2026, with prices from $464 to $3,151, a $2,687 spread on the same certified stone. Diamond Exchange Canada lists it at $3,151. 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.
