About this 0.55ct lab-grown radiant diamond

This 0.55ct lab-grown radiant 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 LG805609963 or 805609963. Listed at 20 retailers as of November 2, 2026, with prices from $275 to $1,604, a $1,329 spread on the same certified stone. MOH London lists it at $1,604. 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.
