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 LG780661979 or 780661979. Listed at 13 retailers as of November 3, 2026, with prices from $129 to $1,240, a $1,111 spread on the same certified stone. Do Amore Diamonds lists it at $1,240. 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.
