About this 0.55ct lab-grown heart diamond

This 0.55ct 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 LG747548753 or 747548753. Listed at 2 retailers as of October 31, 2026, with prices from €198 to €627, a €429 spread on the same certified stone. Brilliant Earth lists it at €627. 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.
