About this 0.59ct lab-grown oval diamond

This 0.59ct 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 LG844642799 or 844642799. Listed at 14 retailers as of October 29, 2026, with prices from £345 to £1,578, a £1,233 spread on the same certified stone. Riddles Jewelry lists it at £1,578. 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.
