About this 0.73ct lab-grown emerald diamond

This 0.73ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818699370 or 818699370. Listed at 24 retailers as of October 29, 2026, with prices from $291 to $1,496, a $1,205 spread on the same certified stone. Riddles Jewelry lists it at $1,496. 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.
