About this 0.9ct lab-grown oval diamond

This 0.9ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG715595359 or 715595359. Listed at 11 retailers as of October 28, 2026, with prices from £312 to £886, a £574 spread on the same certified stone. Brilliant Earth lists it at £886. 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.
