About this 0.5ct lab-grown radiant diamond

This 0.5ct 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 LG806626007 or 806626007. Listed at 20 retailers as of October 30, 2026, with prices from $134 to $1,386, a $1,252 spread on the same certified stone. MOH London lists it at $1,386. 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.
