About this 0.55ct lab-grown round diamond

This 0.55ct lab-grown round 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 LG739538972 or 739538972. Listed at 18 retailers as of October 29, 2026, with prices from $174 to $1,806, a $1,632 spread on the same certified stone. MOH London lists it at $1,806. 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.
