About this 0.56ct lab-grown round diamond

This 0.56ct lab-grown round 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 LG851604570 or 851604570. Listed at 3 retailers as of October 29, 2026, with prices from $243 to $546, a $303 spread on the same certified stone. Taylor and Hart lists it at $546. 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.
