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 LG632471527 or 632471527. Listed at 24 retailers as of October 27, 2026, with prices from $154 to $1,626, a $1,472 spread on the same certified stone. Queensmith lists it at $1,626. 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.
