About this 0.73ct lab-grown round diamond

This 0.73ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818661972 or 818661972. Listed at 18 retailers as of October 28, 2026, with prices from $327 to $1,725, a $1,398 spread on the same certified stone. Reve Diamonds lists it at $1,725. 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.
