About this 0.99ct lab-grown round diamond

This 0.99ct lab-grown round 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 LG836619879 or 836619879. Listed at 18 retailers as of October 29, 2026, with prices from $208 to $1,460, a $1,252 spread on the same certified stone. Brilliant Earth lists it at $1,460. 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.
