About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG724581378 or 724581378. Listed at 11 retailers as of October 29, 2026, with prices from $609 to $1,649, a $1,040 spread on the same certified stone. MOH London lists it at $1,649. 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.
