About this 0.52ct lab-grown oval diamond

This 0.52ct 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 LG831697392 or 831697392. Listed at 5 retailers as of October 31, 2026, with prices from £1,000 to £1,154, a £154 spread on the same certified stone. Loose Grown Diamond lists it at £1,154. 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.
