About this 0.83ct lab-grown oval diamond

This 0.83ct lab-grown oval 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 LG818654089 or 818654089. Listed at 17 retailers as of October 29, 2026, with prices from $440 to $2,195, a $1,755 spread on the same certified stone. MOH London lists it at $2,195. 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.
