About this 0.45ct lab-grown oval diamond

This 0.45ct 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 LG844621576 or 844621576. Listed at 20 retailers as of October 29, 2026, with prices from $139 to $809, a $670 spread on the same certified stone. MOH London lists it at $809. 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.
