About this 0.99ct lab-grown radiant diamond

This 0.99ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG692566723 or 692566723. Listed at 25 retailers as of October 27, 2026, with prices from $252 to $1,676, a $1,424 spread on the same certified stone. Queensmith lists it at $1,676. 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.
