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 LG745507159 or 745507159. Listed at 17 retailers as of October 22, 2026, with prices from $164 to $1,844, a $1,680 spread on the same certified stone. MOH London lists it at $1,844. 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.
