About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG811660841 or 811660841. Listed at 18 retailers as of October 25, 2026, with prices from $288 to $1,518, a $1,230 spread on the same certified stone. MOH London lists it at $1,518. 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.
