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 LG810611506 or 810611506. Listed at 18 retailers as of October 30, 2026, with prices from $205 to $1,394, a $1,189 spread on the same certified stone. Michael Trio lists it at $1,394. 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.
