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 LG782608623 or 782608623. Listed at 20 retailers as of November 1, 2026, with prices from $281 to $1,691, a $1,411 spread on the same certified stone. Reve Diamonds lists it at $1,691. 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.
