About this 0.98ct lab-grown cushion diamond

This 0.98ct 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 LG662438951 or 662438951. Listed at 17 retailers as of October 31, 2026, with prices from $374 to $1,690, a $1,316 spread on the same certified stone. Brilliant Earth lists it at $1,690. 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.
