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 LG662461297 or 662461297. Listed at 27 retailers as of October 30, 2026, with prices from $337 to $3,246, a $2,908 spread on the same certified stone. Do Amore Diamonds lists it at $3,246. 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.
