About this 0.57ct lab-grown heart diamond

This 0.57ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816624940 or 816624940. Listed at 18 retailers as of November 4, 2026, with prices from €283 to €1,303, a €1,020 spread on the same certified stone. Reve Diamonds lists it at €1,303. 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.
