About this 0.54ct lab-grown heart diamond

This 0.54ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG728549770 or 728549770. Listed at 18 retailers as of November 4, 2026, with prices from $385 to $2,088, a $1,703 spread on the same certified stone. Reve Diamonds lists it at $2,088. 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.
