About this 0.9ct lab-grown radiant diamond

This 0.9ct 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 LG818659117 or 818659117. Listed at 19 retailers as of October 29, 2026, with prices from $236 to $1,816, a $1,580 spread on the same certified stone. Brilliant Earth lists it at $1,816. 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.
