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 LG812614636 or 812614636. Listed at 15 retailers as of November 4, 2026, with prices from $168 to $998, a $830 spread on the same certified stone. Michael Trio lists it at $998. 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.
