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 LG812621425 or 812621425. Listed at 19 retailers as of November 4, 2026, with prices from $290 to $1,537, a $1,247 spread on the same certified stone. Reve Diamonds lists it at $1,537. 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.
