About this 0.89ct lab-grown cushion diamond

This 0.89ct 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 LG799665366 or 799665366. Listed at 13 retailers as of October 29, 2026, with prices from $700 to $3,204, a $2,504 spread on the same certified stone. MOH London lists it at $3,204. 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.
