About this 0.7ct lab-grown marquise diamond

This 0.7ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817670770 or 817670770. Listed at 20 retailers as of November 3, 2026, with prices from $296 to $1,557, a $1,260 spread on the same certified stone. Reve Diamonds lists it at $1,557. 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.
