About this 0.58ct lab-grown marquise diamond

This 0.58ct 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 LG816603116 or 816603116. Listed at 19 retailers as of November 1, 2026, with prices from $407 to $1,951, a $1,544 spread on the same certified stone. Reve Diamonds lists it at $1,951. 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.
