About this 0.81ct lab-grown round diamond

This 0.81ct lab-grown round 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 LG828686728 or 828686728. Listed at 9 retailers as of October 25, 2026, with prices from $580 to $1,649, a $1,069 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.
