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 LG840635102 or 840635102. Listed at 21 retailers as of November 1, 2026, with prices from $300 to $2,549, a $2,249 spread on the same certified stone. Helzberg Diamonds lists it at $2,549. 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.
