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 LG749509390 or 749509390. Listed at 11 retailers as of October 30, 2026, with prices from $512 to $3,600, a $3,088 spread on the same certified stone. Do Amore Diamonds lists it at $3,600. 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.
