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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816612788 or 816612788. Listed at 17 retailers as of October 30, 2026, with prices from €277 to €1,289, a €1,012 spread on the same certified stone. Reve Diamonds lists it at €1,289. 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.
