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 LG809651405 or 809651405. Listed at 21 retailers as of November 1, 2026, with prices from $298 to $1,745, a $1,447 spread on the same certified stone. Reve Diamonds lists it at $1,745. 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.
