About this 0.99ct lab-grown oval diamond

This 0.99ct lab-grown oval sits in the just-under-one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG815698143 or 815698143. Listed at 18 retailers as of November 3, 2026, with prices from $298 to $2,754, a $2,456 spread on the same certified stone. With Clarity lists it at $2,754. 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.
