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 LG838646071 or 838646071. Listed at 6 retailers as of October 28, 2026, with prices from $389 to $1,346, a $956 spread on the same certified stone. MOH London lists it at $1,346. 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.
