About this 0.68ct lab-grown round diamond

This 0.68ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG788640312 or 788640312. Listed at 21 retailers as of October 28, 2026, with prices from $186 to $1,150, a $964 spread on the same certified stone. Reve Diamonds lists it at $1,150. 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.
