About this 0.34ct lab-grown oval diamond

This 0.34ct lab-grown oval sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG770699587 or 770699587. Listed at 9 retailers as of October 30, 2026, with prices from £157 to £687, a £530 spread on the same certified stone. Zales lists it at £687. 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.
