About this 0.71ct lab-grown oval diamond

This 0.71ct lab-grown oval 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 LG804602928 or 804602928. Listed at 23 retailers as of November 1, 2026, with prices from £157 to £862, a £706 spread on the same certified stone. Reve Diamonds lists it at £862. 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.
