About this 0.9ct lab-grown cushion diamond

This 0.9ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG663407878 or 663407878. Listed at 15 retailers as of October 29, 2026, with prices from $291 to $2,300, a $2,009 spread on the same certified stone. Do Amore Diamonds lists it at $2,300. 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.
