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 LG781639264 or 781639264. Listed at 20 retailers as of November 4, 2026, with prices from $423 to $3,647, a $3,223 spread on the same certified stone. Do Amore Diamonds lists it at $3,647. 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.
