About this 0.99ct lab-grown oval diamond

This 0.99ct 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 LG815680897 or 815680897. Listed at 6 retailers as of October 26, 2026, with prices from $338 to $1,140, a $802 spread on the same certified stone. MOH London lists it at $1,140. 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.
