About this 0.91ct lab-grown marquise diamond

This 0.91ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817670944 or 817670944. Listed at 16 retailers as of October 30, 2026, with prices from $253 to $1,279, a $1,026 spread on the same certified stone. Reve Diamonds lists it at $1,279. 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.
