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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG823695289 or 823695289. Listed at 15 retailers as of October 31, 2026. 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.
