About this 0.99ct lab-grown heart diamond

This 0.99ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG594338252 or 594338252. Listed at 20 retailers as of October 30, 2026, with prices from €227 to €1,396, a €1,169 spread on the same certified stone. Brilliant Earth lists it at €1,396. 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.
