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 LG836619227 or 836619227. Listed at 21 retailers as of November 1, 2026, with prices from €192 to €1,634, a €1,441 spread on the same certified stone. Helzberg Diamonds lists it at €1,634. 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.
