About this 0.48ct lab-grown oval diamond

This 0.48ct lab-grown oval sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG819630878 or 819630878. Listed at 23 retailers as of October 29, 2026, with prices from £115 to £740, a £625 spread on the same certified stone. MOH London lists it at £740. 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.
