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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840629997 or 840629997. Listed at 16 retailers as of November 2, 2026, with prices from $130 to $1,341, a $1,211 spread on the same certified stone. MOH London lists it at $1,341. 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.
