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 November 6, 2026, with prices from $178 to $1,236, a $1,058 spread on the same certified stone. Michael Trio lists it at $1,236. 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.
