About this 0.99ct lab-grown radiant diamond

This 0.99ct lab-grown radiant sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG825664754 or 825664754. Listed at 21 retailers as of October 30, 2026, with prices from $234 to $1,866, a $1,633 spread on the same certified stone. Brilliant Earth lists it at $1,866. 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.
