About this 0.3ct lab-grown oval diamond

This 0.3ct lab-grown oval sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG800638204 or 800638204. Listed at 18 retailers as of October 26, 2026, with prices from £104 to £663, a £560 spread on the same certified stone. MOH London lists it at £663. 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.
