About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion 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 LG662438887 or 662438887. Listed at 18 retailers as of October 29, 2026, with prices from €337 to €1,531, a €1,193 spread on the same certified stone. Brilliant Earth lists it at €1,531. 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.
