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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG660412312 or 660412312. Listed at 22 retailers as of October 29, 2026, with prices from $235 to $1,542, a $1,307 spread on the same certified stone. Reve Diamonds lists it at $1,542. 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.
