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. Listed at 3 retailers as of October 31, 2026, with prices from $367 to $2,474, a $2,107 spread on the same certified stone. Helzberg Diamonds lists it at $2,474. 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.
