About this 0.91ct lab-grown radiant diamond

This 0.91ct 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 LG691592266 or 691592266. Listed at 22 retailers as of October 29, 2026, with prices from $233 to $1,530, a $1,297 spread on the same certified stone. Brilliant Earth lists it at $1,530. 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.
