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 LG754509007 or 754509007. Listed at 21 retailers as of October 29, 2026, with prices from $182 to $1,871, a $1,689 spread on the same certified stone. MOH London lists it at $1,871. 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.
