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 LG638416677 or 638416677. Listed at 19 retailers as of October 25, 2026, with prices from $175 to $1,030, a $855 spread on the same certified stone. MOH London lists it at $1,030. 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.
