About this 0.75ct lab-grown oval diamond

This 0.75ct 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 LG839698257 or 839698257. Listed at 21 retailers as of October 31, 2026, with prices from £219 to £1,125, a £906 spread on the same certified stone. Riddles Jewelry lists it at £1,125. 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.
