About this 0.78ct lab-grown heart diamond

This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG727532786 or 727532786. Listed at 20 retailers as of October 28, 2026, with prices from $252 to $1,276, a $1,024 spread on the same certified stone. Reve Diamonds lists it at $1,276. 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.
