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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG794625128 or 794625128. Listed at 2 retailers as of October 28, 2026, with prices from £432 to £653, a £222 spread on the same certified stone. Brilliant Earth lists it at £653. 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.
