About this 0.51ct lab-grown radiant diamond

This 0.51ct 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 LG747548772 or 747548772. Listed at 19 retailers as of November 2, 2026, with prices from $133 to $1,380, a $1,247 spread on the same certified stone. MOH London lists it at $1,380. 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.
