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 LG815677242 or 815677242. Listed at 20 retailers as of October 30, 2026, with prices from $161 to $1,016, a $855 spread on the same certified stone. Reve Diamonds lists it at $1,016. 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.
