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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG783613698 or 783613698. Listed at 5 retailers as of October 29, 2026, with prices from $735 to $3,372, a $2,637 spread on the same certified stone. MOH London lists it at $3,372. 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.
