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 LG830677873 or 830677873. Listed at 12 retailers as of October 29, 2026, with prices from $133 to $1,321, a $1,188 spread on the same certified stone. MOH London lists it at $1,321. 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.
