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 LG807613990 or 807613990. Listed at 15 retailers as of November 4, 2026, with prices from $510 to $3,398, a $2,888 spread on the same certified stone. Do Amore Diamonds lists it at $3,398. 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.
