About this 0.77ct lab-grown cushion diamond

This 0.77ct 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 LG847667822 or 847667822. Listed at 2 retailers as of October 28, 2026, with prices from $435 to $1,179, a $744 spread on the same certified stone. MOH London lists it at $1,179. 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.
