About this 0.77ct lab-grown cushion diamond

This 0.77ct 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 LG741580439 or 741580439. Listed at 16 retailers as of November 3, 2026, with prices from €372 to €1,612, a €1,240 spread on the same certified stone. MOH London lists it at €1,612. 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.
