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 LG585318250 or 585318250. Listed at 20 retailers as of October 30, 2026, with prices from £162 to £876, a £714 spread on the same certified stone. Reve Diamonds lists it at £876. 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.
