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 LG818663094 or 818663094. Listed at 20 retailers as of October 30, 2026, with prices from $202 to $1,435, a $1,233 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.
