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 $142 to $1,008, a $866 spread on the same certified stone. Reve Diamonds lists it at $1,008. 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.
