About this 0.65ct lab-grown marquise diamond

This 0.65ct 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 LG743537975 or 743537975. Listed at 16 retailers as of October 28, 2026, with prices from $273 to $1,920, a $1,647 spread on the same certified stone. Do Amore Diamonds lists it at $1,920. 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.
