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 LG836614533 or 836614533. Listed at 20 retailers as of October 31, 2026, with prices from $306 to $1,708, a $1,402 spread on the same certified stone. Brilliant Earth lists it at $1,708. 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.
