About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG804628346 or 804628346. Listed at 11 retailers as of October 29, 2026, with prices from $435 to $1,242, a $807 spread on the same certified stone. MOH London lists it at $1,242. 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.
