About this 0.51ct lab-grown radiant diamond
This 0.51ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG813608954 or 813608954. Listed at 18 retailers as of October 30, 2026, with prices from $251 to $1,714, a $1,463 spread on the same certified stone. Michael Trio lists it at $1,714. 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.
