About this 0.99ct lab-grown round diamond

This 0.99ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG804649921 or 804649921. Listed at 19 retailers as of October 31, 2026, with prices from $381 to $2,129, a $1,748 spread on the same certified stone. Brilliant Earth lists it at $2,129. 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.
