About this 0.9ct lab-grown cushion diamond

This 0.9ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG815698158 or 815698158. Listed at 15 retailers as of November 3, 2026, with prices from $807 to $2,822, a $2,016 spread on the same certified stone. Brilliant Earth lists it at $2,822. 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.
