About this 0.53ct lab-grown radiant diamond

This 0.53ct 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 LG818663249 or 818663249. Listed at 21 retailers as of November 1, 2026, with prices from $225 to $1,435, a $1,210 spread on the same certified stone. Reve Diamonds lists it at $1,435. 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.
