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 LG677512502 or 677512502. Listed at 30 retailers as of October 30, 2026, with prices from $262 to $2,250, a $1,988 spread on the same certified stone. Do Amore Diamonds lists it at $2,250. 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.
