About this 0.4ct natural emerald diamond

This 0.4ct natural emerald sits in the sub-half-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5212326556. Listed at 2 retailers as of October 25, 2026, with prices from $410 to $676, a $266 spread on the same certified stone. Adiamor lists it at $676. 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.
