About this 0.66ct lab-grown radiant diamond

This 0.66ct 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 LG809635473 or 809635473. Listed at 19 retailers as of November 1, 2026, with prices from $258 to $1,569, a $1,311 spread on the same certified stone. Michael Trio lists it at $1,569. 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.
