About this 0.85ct lab-grown oval diamond

This 0.85ct 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 LG839698260 or 839698260. Listed at 21 retailers as of October 29, 2026, with prices from £246 to £1,277, a £1,031 spread on the same certified stone. Riddles Jewelry lists it at £1,277. 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.
