About this 0.7ct lab-grown oval diamond

This 0.7ct lab-grown oval 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 LG818662731 or 818662731. Listed at 20 retailers as of October 30, 2026, with prices from £225 to £1,055, a £830 spread on the same certified stone. Reve Diamonds lists it at £1,055. 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.
