About this 0.81ct lab-grown emerald diamond

This 0.81ct lab-grown emerald sits in the just-under-one-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG604379117 or 604379117. Listed at 23 retailers as of October 31, 2026, with a 376% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
