About this 0.52ct lab-grown radiant diamond

This 0.52ct lab-grown radiant 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 LG818661970 or 818661970. Listed at 18 retailers as of November 1, 2026, with prices from $384 to $2,081, a $1,697 spread on the same certified stone. Reve Diamonds lists it at $2,081. 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.
