About this 0.51ct lab-grown radiant diamond

This 0.51ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG786676873 or 786676873. Listed at 19 retailers as of October 27, 2026, with prices from $205 to $1,194, a $989 spread on the same certified stone. MOH London lists it at $1,194. 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.
