About this 0.77ct lab-grown heart diamond

This 0.77ct lab-grown heart 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 LG799605259 or 799605259. Listed at 19 retailers as of November 1, 2026, with prices from $250 to $1,355, a $1,105 spread on the same certified stone. Reve Diamonds lists it at $1,355. 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.
