About this 0.78ct natural cushion diamond

This 0.78ct natural 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 stated by the retailer rather than the lab and certified by GIA 2557483521. Listed at 12 retailers as of November 4, 2026, with prices from $2,853 to $6,708, a $3,854 spread on the same certified stone. MOH London lists it at $6,708. 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.
