About this 0.91ct lab-grown cushion diamond

This 0.91ct 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 LG790605623 or 790605623. Listed at 16 retailers as of November 4, 2026, with prices from $375 to $2,811, a $2,435 spread on the same certified stone. Brilliant Earth lists it at $2,811. 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.
