About this 0.83ct lab-grown oval diamond

This 0.83ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG837648654 or 837648654. Listed at 21 retailers as of October 29, 2026, with prices from £242 to £1,255, a £1,013 spread on the same certified stone. Riddles Jewelry lists it at £1,255. 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.
