About this 0.75ct lab-grown cushion diamond

This 0.75ct 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 LG667401615 or 667401615. Listed at 24 retailers as of October 31, 2026, with prices from $427 to $3,730, a $3,303 spread on the same certified stone. Do Amore Diamonds lists it at $3,730. 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.
