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 LG790630389 or 790630389. Listed at 19 retailers as of October 29, 2026, with prices from $203 to $1,187, a $984 spread on the same certified stone. MOH London lists it at $1,187. 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.
