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 LG790611987 or 790611987. Listed at 19 retailers as of October 30, 2026, with prices from $280 to $1,353, a $1,073 spread on the same certified stone. Reve Diamonds lists it at $1,353. 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.
