About this 0.78ct lab-grown radiant diamond

This 0.78ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818658786 or 818658786. Listed at 18 retailers as of November 4, 2026, with prices from $610 to $2,728, a $2,118 spread on the same certified stone. Reve Diamonds lists it at $2,728. 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.
