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 LG578313002 or 578313002. Listed at 20 retailers as of October 29, 2026, with prices from $129 to $1,199, a $1,070 spread on the same certified stone. MOH London lists it at $1,199. 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.
