About this 0.52ct lab-grown heart diamond

This 0.52ct 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 LG812621564 or 812621564. Listed at 19 retailers as of November 1, 2026, with prices from $220 to $1,182, a $962 spread on the same certified stone. Reve Diamonds lists it at $1,182. 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.
