About this 0.68ct lab-grown radiant diamond

This 0.68ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG643411996 or 643411996. Listed at 20 retailers as of October 29, 2026, with prices from $332 to $1,890, a $1,558 spread on the same certified stone. Kay Jewelers lists it at $1,890. 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.
