About this 0.55ct lab-grown round diamond

This 0.55ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG659455058 or 659455058. Listed at 19 retailers as of October 22, 2026, with prices from $182 to $1,889, a $1,707 spread on the same certified stone. MOH London lists it at $1,889. 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.
