About this 0.55ct lab-grown round diamond

This 0.55ct 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 LG739504406 or 739504406. Listed at 19 retailers as of October 29, 2026, with prices from $144 to $1,014, a $870 spread on the same certified stone. Reve Diamonds lists it at $1,014. 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.
