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 LG578331670 or 578331670. Listed at 20 retailers as of October 30, 2026, with prices from €194 to €1,051, a €857 spread on the same certified stone. Reve Diamonds lists it at €1,051. 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.
