About this 0.71ct lab-grown radiant diamond

This 0.71ct 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 LG811649368 or 811649368. Listed at 14 retailers as of October 31, 2026, with prices from $206 to $1,109, a $903 spread on the same certified stone. Michael Trio lists it at $1,109. 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.
