About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG830618736 or 830618736. Listed at 4 retailers as of October 29, 2026, with prices from $316 to $550, a $234 spread on the same certified stone. Brilliant Earth lists it at $550. 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.
