About this 0.68ct lab-grown round diamond

This 0.68ct 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 LG583301664 or 583301664. Listed at 19 retailers as of October 28, 2026, with prices from $194 to $1,174, a $980 spread on the same certified stone. Reve Diamonds lists it at $1,174. 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.
