About this 0.99ct lab-grown emerald diamond

This 0.99ct lab-grown emerald sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG674544435 or 674544435. Listed at 19 retailers as of October 28, 2026, with prices from $1,035 to $1,470, a $435 spread on the same certified stone. Brilliant Earth lists it at $1,470. 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.
