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 LG818608863 or 818608863. Listed at 7 retailers as of October 29, 2026, with prices from €295 to €1,025, a €730 spread on the same certified stone. MOH London lists it at €1,025. 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.
