About this 0.77ct lab-grown radiant diamond

This 0.77ct lab-grown radiant 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 LG739534722 or 739534722. Listed at 20 retailers as of October 30, 2026, with prices from $267 to $1,407, a $1,140 spread on the same certified stone. Reve Diamonds lists it at $1,407. 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.
